1 New in release 0.99 (XXX XX, XXXX)
3 New in release 0.98 (Feb 05, 2009)
5 * Native support for BigInteger is now provided using the GMP
6 library. A new option, --enable/disable-gmp is provided, and
7 the option is enabled by default if GMP is found.
8 * Classpath now makes use of a new StringBuilder implementation
9 internally called CPStringBuilder. In addition to being
10 unsynchronised, like StringBuilder, this also avoids copying the
11 array when toString or substring is called. While StringBuffer/Builder
12 always retain their own array, which is only altered during resizing,
13 CPStringBuilder gives away its array when the result is generated
14 by toString()/substring() and starts afresh. The default capacity of
15 CPStringBuilder can also be configured using the
16 gnu.classpath.cpstringbuilder.capacity property. (PR21869)
17 * gjdoc is now built as part of tools.zip.
18 * Import of the Java Activation Framework from ClasspathX to provide
19 javax.activation (part of 1.6).

45 Runtime interface changes:
47 * VMSecureRandom has moved to gnu.java.security.jce.prng.VMSecureRandom
48 as part of the fix for PR38417.
49 * gnu.java.lang.VMCPStringBuilder has been added and should be added to
50 avoid the inefficency of reflection when creating non-copied String objects.
52 Bug fixes in release 0.97.2 (Jun 06, 2007)
54 * Include headers in the release tarball.
55 * Allow the building of tools to be optional.
56 * Only check for a Java compiler when required.

71 * Include documentation for JSR166 (java.util.concurrent)
72 * Fix STaX API compatability.
73 * Include the tools properties file in the release tarball.
75 New in release 0.97 (Feb 22, 2007)
79 * A copy of javah (to produce C header files from Java source code)
80 is now required to generate the files in include.
81 * The javac check has been changed so that it attempts to find ecj,
82 javac and gcj (in that order). You may override this by using
83 JAVAC=<preferred javac>
85 Runtime interface changes:
87 * Removed VMFloat.floatToIntBits amd VMDouble.doubleToLongBits.
88 * Added new getParameterAnnotations() methods in Constructor and Method.
90 New in release 0.96.1 (Oct 16, 2007)
92 * Small compile, configure and build fixes.
94 New in release 0.96 (Oct 15, 2007)
96 * New experimental GStreamer javax.sound peer (see README.gstreamer)
97 * The JNI interface has been updated to 1.6
98 * Better support for the OpenJDK javac compiler
99 * Support for using javah via tools.zip and com.sun.tools.javah.Main
100 * Much improved Escher AWT peers
101 * Many bug fixes including improvements to AWT and Swing support
103 Runtime interface changes:
105 * Add VMFloat.toString(float) and VMFloat.parseFloat(String). Default
106 implementations are the same as previous behavior.
107 * Add new default implementations of VMMemoryMXBean.getHeapUsage()
108 and VMMemoryMXBean.getNonHeapUsage() via iteration over the memory
109 pools of the appropriate type.
111 New in release 0.95 (Apr 23, 2007)
113 * Full merge of 1.5 generics work.
114 * Added 1.6 java.util.ServiceLoader support.
115 * The ASM library is now included. A separate copy is no longer
116 needed. gjavah works out of the box now.
117 * The setReadTimeout and getReadTimeout methods have been added to
118 java.net.URLConnection. They are now fully implemented for http URLs.
119 * The java.lang.management implementation now includes the new features
121 * java.util.TimeZone now reads time zone information from the system
122 zoneinfo files (see also runtime interface changes below).
123 * The collection classes have been updated to support all the 1.6
125 * java.util.spi 1.6 package has been added and is used in java.text.
126 * Bootstrappable with OpenJDK javac compiler
127 (use configure --with-javac).
128 * Large speedups (and locking behaviour updated) in Graphics2D cairo
129 and freetype support.
130 * Better detection of browser plugin mechanism for mozilla, iceweasel,
131 firefox on various platforms.
132 * Inclusion of generic javadoc classes in tools.zip to support more
133 javadoc processing tools.
134 * Added documentation for command lines options for the included GNU
135 Classpath Tools gjar, gjavah, gnative2ascii, gorbd, grmid,
136 grmiregistry, gserialver and gtnameserv.
138 Runtime interface changes:
140 * gnu.java.lang.management.VMThreadMXBeanImpl has gained three new
141 optional native methods to allow the 1.6 version of the threading
142 bean to be supported. One (getMonitorInfo) fills in information
143 about object monitor locks held by a thread and is only required
144 if the monitoring of object monitor locks is supported by the VM.
145 The other two (findDeadlockedThreads and getLockInfo) are related
146 to ownable synchronizers (part of the java.util.concurrent suite)
147 and only required if monitoring of locks relating to these is
149 * java.util.VMTimeZone and java.util.TimeZone have been refactored
150 to simplify the reference implementation. VMTimeZone.readtzFile()
151 and VMTimeZone.skipFully() have been removed, and a new method
152 VMTimeZone.readSysconfigClockFile() has been introduced.
153 * VMs need to set the system property "gnu.java.util.zoneinfo.dir"
154 to point to the directory where zoneinfo files live. In libgcj
155 this is set to the value of the TZDATA environment variable, or
156 "/usr/share/zoneinfo" if this is not set.
157 * VMFile has been extended to support new 1.6 methods (canExecute,
158 setReadable, setWritable, setExecutable).
160 New in release 0.93 (Dec 8, 2006)
162 * CORBA objects that exist on the same virtual machine and only are connected
163 to another ORB are now accessed directly and no longer via network. It is
164 the same feature that RMI implementation provides. These faster calls should
165 be completely transparent, as the parameters are cloned, where required.
166 Currently the direct calls are only possible for the non-deprecated objects
167 that are connected to the ORB via POA.
168 * The 'javah' tool has been added. It requires the ASM library
169 (see asm.objectweb.org); it can be enabled with the --with-asm
171 * Added the rmi and corbaname URL context factories for JNDI.
172 * Fixes in the JNDI InitialContext now allows to plug-in user implementation.
173 * Removed currentClassLoader method from
174 vm/reference/java/io/ObjectInputStream.java.
175 * Added firstNonNullClassLoader method to
176 vm/reference/gnu/classpath/VMStackWalker.java. VMs are encouraged to
177 provide a more efficient implementation.
178 * Added aton method to vm/reference/java/net/VMInetAddress.java.
179 * NetworkInterface has been implemented for systems that provide the
180 `getifaddrs' function.
181 * java.nio.channels.Selector implementations have been added that use
182 the kqueue notification mechanism on Mac OS X and *BSD, and that use
183 the epoll notification mechanism on Linux 2.6.
184 * java.nio has been refactored to support more non-blocking operations
185 natively. Blocking IO classes have been refactored to call
186 non-blocking classes. Non-blocking accepts, connects, and
187 scatter-gather IO should now be better supported.
188 * HTML support for Swing has been greatly enhanced.
190 Runtime interface changes:
192 * java.net.VMNetworkInterface and java.net.NetworkInterface have been
193 updated to keep native-modified state in the former, and to simplify
194 the native code in our reference implementation.
195 * gnu.java.nio.VMChannel has been expanded to better support native
196 non-blocking IO. Most native state data (such as file descriptor
197 integers) has been abstracted away into private state in the runtime
199 * gnu.java.nio.VMPipe has been similarly changed.
200 * gnu.java.net.VMPlainSocketImpl has been changed to remove some
201 functionality now provided by VMChannel; datagram socket-specific
202 methods have also been moved here, deprecating VMPlainDatagramSocketImpl.
203 * gnu.java.net.VMPlainDatagramSocketImpl removed.
205 New in release 0.92 (Aug 9, 2006)
207 * GConf is used as a backend for java.util.prefs. GNU Classpath
208 thanks to Mario Torre for this contribution!
209 * libjawtgnu.so has been renamed libjawt.so for binary compatibility.
210 libjawt.so should be installed in a VM-specific directory rather
211 than directly in /usr/lib. Proprietary VMs put their libjawt.so
212 implementations in VM-specific directories but search /usr/lib first.
213 If GNU Classpath's libjawt.so is installed in /usr/lib it will create
214 problems for people who use a proprietary VM to run AWT Native
215 Interface applications.
216 * The GdkGraphics2D backend has been made the default. There is no
217 longer an explicit dependency on Cairo, the --enable-gtk-cairo
218 configure option is gone, and GTK 2.8 or higher is now required to
220 * A Mozilla plugin, 'gcjwebplugin', is now included. It introduces a
221 dependency on the Mozilla plugin support headers and libraries.
222 * New java implementations of png and gif imageio readers and writers.
223 * A tools.texinfo document has been created and now includes
229 * Several new tools are now included:
236 A new configure option --enable-tool-wrappers causes wrapper
237 binaries to be built for VMs that support the JNI Invocation API.
238 * We've imported the JSR 166 (concurrency) reference implementation.
239 * javax.sound.midi providers have been added to read and
240 write standard MIDI files.
241 * A javax.sound.sampled .au and .wav file readers have been added.
242 * New Java Virtual Machine Tool Interface header, jvmti.h.
243 * AWT peers for X Windows based on Escher (a pure java X protocol
244 implementation) have been added. So far it supports AWT 1.1 style
245 Graphics, image loading via ImageIO (PNG, GIF and BMP images in this
246 release), top level components as well as mouse and keyboard input.
247 It is capable of running many Swing applications. Graphics2D and
248 AWT widgets are not yet supported with this peer set.
249 * GConf based util.peers backend (see the --enable-gconf-peer and
250 --enable-default-preferences-peer configure options).
251 * Support for batch importing trusted certificates for use with ssl
252 connections (see script/import-cacerts.sh).
253 * NIO scatter-gather channel support.
255 Runtime interface changes:
257 * A new class, VMURLConnection, is used to implement
258 URLConnection.guessContentTypeFromStream. The reference
259 implementation uses libmagic (and falls back to doing nothing if
260 libmagic is not available).
261 * The method gnu.java.io.PlatformHelper.toCanonicalForm() has been
262 replaced with a JNI implementation of VMFile.toCanonicalForm() for
264 * A new class, VMRuntimeMXBeanImpl, is used to implement
265 the low-level support of the runtime management bean.
266 VMs should use it to supply the input arguments and start
267 time of the VM. In addition, one of sun.boot.class.path
268 or java.boot.class.path should be defined by the VM to
269 support the optional boot class path access functionality.
270 * The Unsafe class was moved back to the place expected by the JSR 166
271 reference implementation. We've also added a couple other new VM
272 classes to support the JSR 166 code -- sun.reflect.Reflection and
273 sun.reflect.misc.ReflectUtil.
274 * Another new class, VMClassLoadingMXBeanImpl, is used to implement
275 the low-level support of the class loading management bean.
276 VMs need to supply it with information about how many classes
277 are currently loaded, how many have been unloaded and whether
278 verbose class loading output is on or off. Provision should also
279 be made for the latter to be toggled at runtime.
280 * VMThreadMXBeanImpl is used to implement the low-level support
281 of the thread management bean. Providing this interface requires
282 providing a fair amount of information about threads, including
283 optional time and contention monitoring, and instances of the
284 new ThreadInfo class in java.lang.management. getState() has also
285 been added to the VMThread interface; this is required by the bean
286 as well as java.lang.Thread.
287 * VMMemoryMXBeanImpl is used to implement the low-level support
288 of the memory management bean. Providing this interface requires
289 providing information about the levels of heap and non-heap memory,
290 and the number of objects eligible for garbage collection.
291 * VMCompilationMXBeanImpl is used to allow for optional compilation
292 time support for Just-In-Time compilers.
293 * VMMemoryPoolMXBeanImpl is used to implement the low-level support
294 of the memory pool beans. Providing this interface requires
295 providing memory usage statistics for each supported bean.
296 * VMManagementFactory provides the names of the memory pools,
297 memory managers and garbage collectors maintained by the virtual
298 machine. These are used to create the beans by the ManagementFactory.
299 * VMMemoryManagerMXBeanImpl and VMGarbageCollectorMXBeanImpl provide
300 low-level support for memory managers (including the specific subclass
301 of garbage collecting memory managers). The interfaces for these
302 require no more than enumerating the number of collections and the
303 time spent (for garbage collectors) and a relationship to the memory
304 pools (for all), along with a validity check.
306 New in release 0.91 (May 15, 2006)
308 * Experimental activation (java.rmi.activation) support, including RMI
309 activation daemon and persistent naming service tools.
310 * Experimental printing support: The API implementation of the javax.print
311 packages has been finished and work on the printing provider implementation
312 started. Currently supported features from the Java Print Service API are
313 print service discovery (CUPS registered printers), single document print
314 jobs and support for client-formatted print data. An example application
315 (see: examples/gnu/classpath/examples/print/Demo) has been added to show
316 the API usage for service discovery and printing of files.
317 * The GTKToolkit now gives access to the both the system clipboard and
319 * Custom mouse cursor support has been added to the gtk+ peers. And cursors
320 can now also be set on light-weight components.
321 * Free Swing improvements: Support for OceanTheme has been mostly completed
322 and turned on as default Metal theme. X11-style Copy and Paste behavior in
323 text components with the middle mouse button. Support cursor changes on
324 various components when resizing. Support for Look and Feel window
325 decorations has been added.
326 * Updated locale data information to CLDR 1.3.
327 * Various bugs in Classpath's SecureRandom implementations have been
328 fixed; that class now respects the "securerandom.source" security
329 property and the "java.security.egd" system property.
330 * Support for assistive technologies has been added to AWT and Swing.
332 Runtime interface changes:
334 * A new class, VMArray, is now available which separates the native
335 array creation method from java.lang.reflect.Array.
336 * A new class, gnu.classpath.Unsafe, is provided for handling the
337 new low-level operations required by java.util.concurrent.
338 * The reference implementations of Method, Constructor, and Field
339 now have a new native getModifiersInternal() method. The public
340 getModifiers() method in each case has been rewritten in terms of
342 * The reference implementation of VMThread has been updated to handle
343 the new Thread.UncaughtExceptionHandler support.
344 * A new class, java.security.VMSecureRandom, is now available that is
345 used to generate random numbers for seeding cryptographically-secure
346 pseudo-random number generators.
347 * VMClass and the reference implementations of Method, Constructor and Field
348 now include a number of 1.5 methods imported from the generics branch.
349 These are all optional (in the sense that the methods associated with them
350 merely fail on use if the VM doesn't provide them, rather than the
351 VM failing altogether), but VMs should aim to support them where possible.
352 * The implementation of java.lang.instrument has been merged to the main
353 branch from the generics branch.
354 * The VM interfaces of the main branch and the generics branch are now
355 consistent with one another. As a result, the main branch includes an
356 additional environ() function in VMSystem and an additional argument has
357 been added to nativeSpawn() in VMProcess.
358 * Annotation support is now available in the main branch, if the VM supports
359 it. The VM should implement VMClass.getDeclaredAnnotations,
360 Constructor.getAnnotation, Constructor.getDeclaredAnnotations,
361 Field.getAnnotation, Field.getDeclaredAnnotations, Method.getAnnotation and
362 Method.getDeclaredAnnotations.
363 * java.lang.Package now has a new constructor that takes the defining
364 ClassLoader as an extra argument. If you use a custom version of
365 VMClassLoader, please switch it to use this constructor.
366 * The reference implementation of VMClassLoader.getBootPackages() now
367 reads the META-INF/INDEX.LIST resource using the java.boot.class.path
370 New in release 0.90 (March 6, 2006)
372 * Free Swing improvements: JTable columns are rearrangeable and
373 resizeable with mouse. Painting and scrolling are now much
374 faster. Plain text components now support highlighting and
375 copy+paste to the system clipboard. Support for styled text has been
376 improved, including some very basic HTML support. JFileChooser is
377 now usable. Global event dispatching has been implemented. Memory
378 consumption of Swing components has been reduced. Lots of general
379 bugfixes. Added new system property to turn off Graphics2D use in
380 Swing, even if Graphics2D is available: gnu.javax.swing.noGraphics2D
382 * AWT. Improved support for mixing "lightweight" and "heavyweight"
383 Components in Containers. Better support for dynamically updated
384 menus. Better 1.0 event model support for Scrollbars. Better class
385 documentation of gtk+ awt peers.
387 * GNU Crypto and Jessie have been merged into GNU Classpath; this
388 provides Classpath with a wide array of cryptographic algorithms
389 (ciphers, message digests, etc.) and implementations of SSL version
390 3 and TLS version 1. These roughly complement the public
391 `java.security.' `javax.crypto,' and `javax.net.ssl' packages, and
392 are service providers implementing the underlying algorithms.
394 * Updated HTTP and FTP URLConnection protocol handlers. HTTPS support
397 * Unicode 4.0.0 is supported. Character now includes support for using
398 ether a char or an int to identify code points.
400 * More correct handling of Object methods and serialization support
401 for Proxy and abstract classes.
403 * The new folder tools includes GIOP and RMI stub and tie source code
404 generators, IOR parser and both transient and persistent GIOP naming
407 * Added experimental support for dynamic creation of the RMI stubs
408 using proxy classes. The rmic compiler is no longer required (unless
409 for research and specific stubs).
411 * XML validaton support for RELAX NG and W3C XML schema namespace
412 URIs. RELAX NG pluggable XML schema datatype library API and an
413 implementation for XML Schema Datatypes
414 (http://www.w3.org/TR/xmlschema-2/).
416 * Updated StAX implementaton to be compatible with final JSWDP 2.0.
418 * The default back end for java.util.prefs has been changed. The new
419 default is capable of saving and restoring preferences to and from
422 * javax.imageio.plugins.bmp implementation.
424 * Added --enable-collections configure option which builds
425 "collections.jar", a 1.1 VM compatibility jar.
427 * gnu.regexp updated from GNU/Posix syntax to support util.regex
428 syntax including various Unicode blocks, categories and properties.
430 Runtime interface changes:
432 * A new class, VMMath, is now available which separates the native
433 mathematical functions from java.lang.Math. The previous fdlibm
434 implementation now forms the reference material for this class.
436 * Updated VMObjectInputStream class to return Thread context class
437 loader if no other class loader is found.
439 * Updated documentation on InstrumentationImpl in vmintegration guide.
441 New in release 0.20 (Jan 13, 2006)
443 * New StAX pull parser and SAX-over-StAX driver. Lots of DOM, SAX/StAX,
444 XPath and XSLT improvements. Support for XInclude and XML Base added.
445 Conformance is now regularly tested against various test-suites at
446 http://builder.classpath.org/xml/ See also doc/README.jaxp.
448 * Full beans XMLEncoder implementation.
450 * javax.sound.sampled implementation.
452 * javax.print.attribute and javax.print.event implementated.
454 * Lots of new datatransfer, print swing and swing.text work and optimization.
456 * Additional 1.5 support. Including new (separate) generic branch release.
458 * SecurityManager cleanups and start of review of all Permission checks
459 (includes adding lots of new checks to the Mauve test-suite).
461 * Buildable on cygwin.
463 * Fully buildable as "in-workspace" library-plus-vm inside (native) Eclipse
464 see http://developer.classpath.org/mediation/ClasspathHackingWithEclipse
466 * Full example that shows a real world CORBA and Free Swing implementation.
467 See examples/gnu/classpath/examples/CORBA/swing/README.html
469 * A list of bug fixes can be found at:
470 http://gcc.gnu.org/bugzilla/buglist.cgi?product=classpath&target_milestone=0.20
472 Runtime interface changes:
474 * New method VMStackWalker.getClassLoader() was added to avoid an infinite
475 loop between getCallingClassLoader() and Class.getClassLoader().
477 * The included fdlibm implementation has seen several cleanups to handle
478 new architectures and namespacing issues (in particular for ppc, darwin
479 and non-C99 compilers). Please double check any arithmetic test against
480 new platforms/runtimes.
482 * The gnu.java.net.Plain[Datagram]Socket implementations have been
483 turned into VM reference classes with JNI/Posix implementations.
485 New in release 0.19 (Nov 2, 2005)
487 * The Swing RepaintManager has been reworked for more efficient painting,
488 especially for large GUIs.
490 * The Swing layout manager OverlayLayout has been implemented, the BoxLayout
491 has been rewritten to make use of the SizeRequirements utility class and
492 caching for more efficient layout.
494 * Improved accessibility support for Swing.
496 * The java.net.HttpURLConnection implementation no longer buffers the
497 entire response body in memory. This means that response bodies
498 larger than available memory can now be handled.
500 * The Andrew Watson, Vice President and Technical Director of the Object
501 Management Group, has officially assigned us 20 bit Vendor Minor Code Id:
502 0x47430 ("GC") that will mark remote Classpath - specific system exceptions.
503 Obtaining the VMCID means that GNU Classpath now is a recogniseable type of
504 node in a highly interoperable CORBA world.
506 * Classpath now includes the first working draft to support the RMI over
507 IIOP protocol. The current implementation is capable for remote invocations,
508 transferring various Serializables and Externalizables via RMI-IIOP protocol.
509 It can flatten graphs and, at least for the simple cases, is interoperable
512 * Qt4 configury switches for OS-X. Additional to the --enable-qt-peer, OS-X
513 users with a Qt4 installation can build the qt-peers with the argument
514 --with-qt4dir=<Qt4-installation-dir>.
516 * Significant progress has been made in the implementation of the
517 javax.swing.plaf.metal.* package, with most UI delegates in a working state
518 now. Please test this with your own applications and provide feedback that
519 will help us to improve this package.
521 * The GUI demo (gnu.classpath.examples.swing.Demo) has been extended to
522 highlight various features in our free-swing implementation. And includes
523 a look and feel switcher (Metal default, Ocean or GNU).
525 Runtime interface changes:
527 * Changed implementation of VMClassLoader.getPackage(s) : new method
528 VMClassLoader.getBootPackages should be implemented by the vm, and sould
529 return a string array of boot package names ("java.lang", "java.net", ...).
530 Feedback from vm implementors for usability and relevance of the
531 getBootPackages method would be greatly appreciated.
533 New in release 0.18 (Sep 6, 2005)
535 * GNU JAWT implementation, the AWT Native Interface, which allows direct
536 access to native screen resources from within a Canvas's paint method.
537 GNU Classpath Examples comes with a Demo, see examples/README.
538 * awt.datatransfer updated to 1.5 with supports for FlavorEvents.
539 The gtk+ awt peers now allow copy/paste of text, images, uris/files
540 and serialized objects with other applications and tracking
541 clipboard change events with gtk+ 2.6 (for gtk+ 2.4 only text and
542 serialized objects are supported). A GNU Classpath Examples
543 datatransfer Demo was added to show the new functionality.
544 * org.omg.PortableInterceptor and related functionality in other packages
546 - The sever and client interceptors work as required since 1.4.
547 - The IOR interceptor works as needed for 1.5.
548 * The org.omg.DynamicAny package is completed and passes the prepared tests.
549 * The Portable Object Adapter should now support the output of the
550 recent IDL to java compilers. These compilers now generate servants and
551 not CORBA objects as before, making the output depended on the existing
552 POA implementation. Completing POA means that such code can already be
553 tried to run on Classpath. Our POA is tested for the following usager
555 - POA converts servant to the CORBA object.
556 - Servant provides to the CORBA object.
557 - POA activates new CORBA object with the given Object Id (byte array)
558 that is later accessible for the servant.
559 - During the first call, the ServantActivator provides servant for this
560 and all subsequent calls on the current object.
561 - During each call, the ServantLocator provides servant for this call
563 - ServantLocator or ServantActivator forwards call to another server.
564 - POA has a single servant, responsible for all objects.
565 - POA has a default servant, but some objects are explicitly connected
566 to they specific servants.
567 The POA is verified using tests from the former cost.omg.org.
568 * The javax.swing.plaf.multi.* package is now implemented.
569 * Editing and several key actions for JTree and JTable were implemented.
570 * Lots of icons and look and feel improvements for Free Swing basic and
571 metal themes were added. Try running the GNU Classpath Swing Demo in
572 examples (gnu.classpath.examples.swing.Demo) with:
573 -Dswing.defaultlaf=javax.swing.plaf.basic.BasicLookAndFeel
574 -Dswing.defaultlaf=javax.swing.plaf.metal.MetalLookAndFeel
575 * Start of styled text capabilites for java.swing.text.
576 * NIO FileChannel.map implementation, fast bulk put implementation for
577 DirectByteBuffer (speeds up this method 10x).
578 * Split gtk+ awt peers event handling in two threads and improve gdk lock
579 handling (solves several AWT lock ups).
580 * Speed up awt Image loading.
581 * Updated TimeZone data against Olson tzdata2005l.
582 * Make zip and jar UTF-8 "clean".
583 * "native" code builds and compiles (warning free) on Darwin and Solaris.
585 Runtime interface changes:
587 * All native resource "pointers" in the VM interface classes are now exposed
588 as gnu.classpath.Pointer objects. This might impact runtimes that
589 optimize and support java.nio.DirectByteBuffers. Creating these classes
590 and accessing the contents as void * pointers for the native reference JNI
591 implementation is done through the JCL_NewRawDataObject and JCL_GetRawData
593 * Simplified the Class/VMClass interface.
594 * Removed loadedClasses map from ClassLoader. It's now the VMs responsibility
595 to manage the list of defined and loaded classes for each class loader.
596 * Moved native methods from java.lang.reflect.Proxy to VMProxy.
597 * Added hook to VMClassLoader to allow VM to do class caching.
599 New Untested/Disabled Features:
601 The following new features are included, but not ready for production
602 yet. They are explicitly disabled and not supported. But if you want
603 to help with the development of these new features we are interested
604 in feedback. You will have to explicitly enable them to try them out
605 (and they will most likely contain bugs). If you are interested in any
606 of these then please join the mailing-list and follow development in
609 * QT4 AWT peers, enable by giving configure --enable-qt-peer.
610 * JDWP framework, enable by deleting the jdwp references from
611 lib/standard.omit and vm/reference/standard.omit. No default
612 implementation is provided. Work is being done on gcj/gij integration.
613 * StAX java.xml.stream, enable by deleting the gnu.xml.stream and
614 java.xml.stream references in lib/standard.omit.
616 New in release 0.17 (Jul 15, 2005)
618 * gnu.xml fix for nodes created outside a namespace context.
619 * Add support for output indenting and cdata-section-elements output
620 instruction in xml.transform.
621 * xml.xpath corrections for cases where elements/attributes might have
622 been created in non-namespace-aware mode. Corrections to handling of
623 XSL variables and minor conformance updates.
624 * DefaultMutableTreeNode preorder, postorder, depthFirst and breadthFirst
625 traversal enumerations implemented.
626 * JInternalFrame colors and titlebar draw properly.
627 * JTree is working up to par (icons, selection and keyboard traversal).
628 * JMenus were made more compatible in visual and programmatic behavior.
629 * JTable changeSelection and multiple selections implemented.
630 * JButton and JToggleButton change states work properly now.
631 * JFileChooser fixes.
632 * revalidate and repaint fixes which make Free Swing much more responsive.
633 * Correctly handle system call interrupts and timeouts in native nio
635 * MetalIconFactory implemented.
636 * Handle image loading errors correctly for gdkpixbuf and MediaTracker.
637 * Added Tree World to GNU Classpath examples Free Swing demo.
638 * FileChannel.lock() and FileChannel.force() implemented.
639 * java.util.logging.FileHandler now rotates files.
640 * Better handle GDK lock. Properly prefix gtkpeer native functions (cp_gtk).
641 * Corba bug fixes and documentation updates.
642 * Updated gcj build infrastructure.
643 * Documentation fixes all over the place.
644 See http://developer.classpath.org/doc/
645 * VM Integration Guide updates with a full section on VM/Classpath hooks.
647 New in release 0.16 (Jun 30, 2005)
649 * Better GTK scrollbar peer implementation when using GTK >= 2.6.
650 * GdkGraphics2D has been updated to use Cairo 0.5.x APIs.
651 * BufferedImage and GtkImage rewrites. All image drawing operations
652 should now work correctly (flipping requires gtk+ >= 2.6)
653 * Future Graphics2D, Image and Text work is documented at:
654 http://developer.classpath.org/mediation/ClasspathGraphicsImagesText
655 * Free Swing Top-Level Compatibility. JFrame, JDialog, JApplet,
656 JInternalFrame, and JWindow are now 1.5 compatible in the sense that you
657 can call add() and setLayout() directly on them, which will have the same
658 effect as calling getContentPane().add() and getContentPane().setLayout().
659 * The JTree interface has been completed. JTrees now recognizes mouse clicks
660 and selections work, but the visual implementation is not yet complete.
661 Work on expansion and collapsing of the tree nodes is being implemented.
662 * BoxLayout works properly now.
663 * Fixed GrayFilter to actually work.
664 * Metal SplitPane implemented.
665 * Lots of free swing text and editor stuff work now.
667 * When gtk+ 2.6 or higher is installed the default log handler will produce
668 stack traces whenever a WARNING, CRITICAL or ERROR message is produced.
670 * The CORBA implementation is now a working prototype that should support
671 features up till 1.3 inclusive.
672 We would invite groups writing CORBA dependent applications to
673 try Classpath implementation, reporting any possible bugs.
675 The CORBA prototype is interoperable with Sun's implementation v 1.4,
676 transferring object references, primitive types, narrow and wide
677 strings, arrays, structures, trees, abstract interfaces and
678 value types (feature of CORBA 2.3) between these two platforms.
679 The remote exceptions are transferred and handled correctly.
680 The stringified object references (IORs) from various sources are
682 The transient (for current session) and permanent (till jre restart)
684 Both Little and Big Endian encoded messages are accepted.
685 The implementation is verified using tests from the former cost.omg.org.
686 The current release includes working examples (see the examples directory),
687 demonstrating the client-server communication, using either CORBA Request
688 or IDL-based stub (usually generated by a IDL to java compiler).
689 These examples also show how to use the Classpath CORBA naming service.
690 The IDL to java compiler is not yet written, but as our library must be
691 compatible, it naturally accepts the output of other idlj implementations.
693 * New --with-vm-classes configure option, and new 'build' setting
694 for --with-glibj. (Only for integrators.)
696 Runtime interface changes:
698 * Start of a generic JDWP framework in gnu/classpath/jdwp.
699 This is unfinished, but feedback (at classpath@gnu.org) from runtime
700 hackers is greatly appreciated. Although most of the work is currently
701 being done around gcj/gij we want this framework to be as VM neutral as
702 possible. Early design is described in:
703 http://gcc.gnu.org/ml/java/2005-05/msg00260.html
704 * Native method VMClass.getModifiers() now takes an additional
706 * Deprecated native method VMClassLoader.defineClass(ClassLoader,
707 String, byte[], int, int) has been replaced by
708 VMClassLoader.defineClass(ClassLoader, String, byte[], int, int,
710 * VMClassLoader.loadClass(String name, boolean resolve) is now native,
711 replacing the former version which just returned null.
712 * Deprecated native method VMClassLoader.getPrimitiveClass(String) has
713 been replaced by new native method VMClassLoader.getPrimitiveClass(char).
714 * Previously empty implementations of methods VMThread.countStackFrames(),
715 VMThrowable.fillInStackTrace(), and VMThrowable.getStackTrace() have
716 been removed; these methods are now native methods.
717 * Fields "exceptionTypes" and "parameterTypes" have been removed from
718 Contructor.java and getExceptionTypes() and getParameterTypes() are
721 New in release 0.15 (Apr 29, 2005)
723 * The old character encoding framework (gnu.java.io.EncodingManager)
724 has been replaced by a system based completely on nio.charset
725 providers. Many converters have been added, both the io, lang and nio
726 frameworks now use the same set of converters and the whole character
727 stream framework (Readers and Writers) have been optimized. For some
728 workloads this leads to 2x till 20x speedups.
730 The default charsets supported are:
732 Cp424, Cp437, Cp737, Cp775, Cp850, Cp852, Cp855, Cp857, Cp860, Cp861,
733 Cp862, Cp863, Cp864, Cp865, Cp866, Cp869, Cp874, ISO_8859_1, ISO_8859_13,
734 ISO_8859_15, ISO_8859_2, ISO_8859_3, ISO_8859_4, ISO_8859_5, ISO_8859_6,
735 ISO_8859_7, ISO_8859_8, ISO_8859_9, KOI_8, MS874, MacCentralEurope,
736 MacCroatian, MacCyrillic, MacDingbat, MacGreek, MacIceland, MacRoman,
737 MacRomania, MacSymbol, MacThai, MacTurkish, US_ASCII, UTF_16, UTF_16BE,
738 UTF_16Decoder, UTF_16Encoder, UTF_16LE, UTF_8, UnicodeLittle, Windows1250,
739 Windows1251, Windows1252, Windows1253, Windows1254, Windows1255,
740 Windows1256, Windows1257, Windows1258.
742 Many more encoding are supported through the new IconvProvider
743 depending on the platform iconv support. GNU libiconv is recommended.
744 The IconvProvider is currently not enabled by default. To enable it
745 define the system property gnu.classpath.nio.charset.provider.iconv=true.
746 Some runtimes might choose to enable this by default by setting it
747 through VMSystemProperties. We would like to get feedback on whether
748 enabling or disabling the IconvProvider by default results in the
751 * Free swing metal and pluggable look and feels have been improved.
752 The GNU Classpath free swing example can now be run with different
753 "skins" by setting the system property swing.defaultlaf to the GNU,
754 Basic or Metal look and feel.
756 * Some of the org.omg.CORBA classes and packages have now been
757 implemented. The Savannah bug tracker contains additional tasks for
758 which we are seeking help.
760 * Fixed compatibility problems in the java.beans which affected
761 Eclipse's Visual Editor Project.
763 * New completely lock free (Inheritable)ThreadLocal implementation.
765 * javax.swing.text.rtf framework added which can handle simple (plain)
768 * Support for parsing html files into Level 2 Document Object Model
769 (org.w3c.dom.html2 and javax.swing.text.html.parser). And a start of
770 javax.swing.text.html framework added.
772 Runtime interface changes:
774 * jni.h changed to better support compiling runtimes implementing jni;
775 see VM integration guide for details.
776 * New --enable-default-toolkit option to configure can be used to set
777 the fully qualified class name of the default AWT toolkit to use.
778 If not given, the old default of gnu.java.awt.peerk.gtk.GtkToolkit
780 * New --disable-core-jni option can be used to disable building the
781 "core" JNI libraries. This is primarily useful if your VM can use the
782 Gtk peers but not the core JNI libraries.
783 * New system property "gnu.classpath.boot.library.path" can be specified
784 to define the location of the JNI libraries. It is by all means meant
785 ONLY for VM implementors and GNU Classpath hackers. See the hacking
786 guide for more information.
787 * The helper methods currentLoader() and allocateObject() for
788 java.io.ObjectInputStream have been moved to a VMObjectInputStream class.
789 Reference implementations are provided.
790 * java.net.InetAddress now uses VMInetAddress for runtime/platform
791 specific methods getLocalHostname(), getHostByAddr() and
792 getHostByName(). java.net.NetworkInterface now uses VMNetworkInterface
793 for runtime/platform specific getInterfaces() support. Default
794 (Posix/GNU JNI) implementations are provided.
795 * VMClass has a new method getModifiers(Class, boolean) which can be
796 used to get the real modifiers for an inner class or the ones
797 specified by the InnerClasses attribute.
798 * All (possible) runtime specific methods of Object and Double are now
799 in VMObject and VMDouble. Where possible generic reference
800 implementations are provided.
801 * The reference implementation of VMClassLoader now handles zip files
802 on the boot loader class path in getResources().
806 New in release 0.14 (Feb 25, 2005)
808 * Character encoders and decoders have been added for:
809 iso-8859-6 (arabic), iso-8859-7 (greek), iso-8859-8 (hebrew),
810 iso-8859-9 (latin-5), iso-8859-13, iso-8859-15 (latin-9), cp1047 (ebcdic),
811 ebcdic-xml-us,ascii, windows-1250, windows-1252, UTF-16BE (Big Endian),
812 UTF-16LE (Little Endian), UTF-32BE (Big Endian), UTF-32LE (Little Endian).
813 * Full documentation for all classes can be generated (again) by using
814 the --with-gjdoc configure option.
815 * javax.awt.imageio support through gdkpixbuf.
817 Runtime interface changes:
819 * VMSecurityManager has been replaced by gnu.classpath.VMStackWalker.
820 currentClassLoader() is no longer needed, and there are also two new
821 methods with non-native implementations. VM implementors are encouraged
822 to provide more efficient versions.
823 * VMRuntime.nativeLoad() now takes an additional ClassLoader parameter.
825 New in release 0.13 (Jan 6, 2005)
827 * The http url protocol handler has been replaced with a full HTTP/1.1
828 version from GNU inetlib.
829 * A new ftp url protocol handler has been added also from GNU inetlib.
830 * java.beans has been updated to 1.4 including support for XMLEncoder
832 * The java.util.Locale support is now based on the Common Locale Data
833 Repository (CLDR) Project (see http://www.unicode.org/cldr/).
834 GNU Classpath provides support for more than 250 locales now.
835 This new support is experimental and the GNU Classpath hackers are
836 working together with runtime developers and the unicode consortium
837 to improve them in the future.
838 If your runtime misdetects your locale or if the default locale gives
839 problems please try running with -Duser.language=en and -Duser.region=US
840 to fall back on a known good locale.
841 * Added implementations of javax.xml (JAXP 1.3), org.xml.sax (SAX2) and
842 org.w3c.dom (DOM Level 3) interfaces. It is possible to switch between
843 different implementations AElfred2, GNU DOM, GNU XSL, libxmlj SAX,
844 libxmlj DOM and libxmlj XSL by setting different system properties.
845 Also provided is a preliminary XPath 1.0 implementation.
846 The libxmlj versions are build around libxml2 and libxslt and have to
847 be enabled during build time by the --enable-xmlj configure flag.
848 The current support is equal to the last released GNU JAXP 1.3 release.
849 These packages will be maintained as part of the GNU Classpath core classes
850 in the future. For more information, conformance results and documentation
851 on selecting different implementations see doc/README.jaxp.
852 * More AWT accessible support.
853 * AWT gtk+ peers component layout, dialog placement, keyboard focus
854 handling and text positioning have been improved.
855 * ImageIO interfaces are more complete.
856 * JList, JTable and JTree have been hugely improved.
857 * java.awt.Robot support with GdkRobot in the gtk+ awt peers.
858 Needs XTest Extension (libXtst) XServer support.
859 * New --disable-examples configure argument.
861 Runtime interface changes:
863 * Added a new method (VMRuntime.enableShutdownHooks) that enables the VM
864 to lazily register an exit handler.
865 * The java.lang.Class constructor now automatically sets the protection
866 domain for array classes, based on the protection domain of the component
868 * New gnu.classpath.VMSystemProperties class. This replaces the
869 system properties initialization in VMRuntime. Note that it is
870 now the VMs responsibility to set one additional property:
871 gnu.cpu.endian should be set to "big" or "little".
872 * VMRuntime.nativeGetLibname() has been renamed to VMRuntime.mapLibraryName()
873 and has only one argument, the name of the library.
874 * String and StringBuffer now call VMSystem.arraycopy() directly and don't
875 go through java.lang.System. Be careful to not initialize java.lang.System
876 early in the bootstrap sequence in your VM runtime interface classes.
877 * Some (wrong) documentation about the behavior of VMThread.sleep(0, 0)
878 has been updated. Also, VMThread.sleep() now has a default non-native
879 implementation, but it is a generic implementation that ignores the
880 nano-seconds argument. Runtime hackers are encouraged to provide a more
882 * There is prelimenary support for nio direct byte buffers.
883 See VMDirectByteBuffer. Please contact the GNU Classpath mailinglist when
884 you add support for this to your runtime.
886 New in release 0.12 (Nov 14, 2004)
888 * GNU Classpath's JAR implementation now has preliminary support for
889 signed entries, for so called "signed JAR" file support. Signed JAR
890 files are one of the key security features of managed runtimes, and
891 allows code to run privileged given unforgeable proofs of identity.
892 * A much improved version of X.509 certificates has been added,
893 including a robust certificate path checking algorithm. Also
894 included is an implementation of the RSA signature scheme.
895 * Full java.awt.color implementation, with all standard ICC profiles,
896 except for PhotoYCC color space.
897 * java.beans 1.4 updates and bug fixes.
898 * java.awt.image support updated to 1.4.
899 * Improved build process. Uses less memory with gcj and C code is
900 buildable with -Werror on most platform. Please configure with
901 --enable-Werror and report any remaining issues.
902 * Big-endian (PowerPC) fixes for native awt GTK+ peers.
903 * Checkstyle support, see scripts/checkstyle-config.xml.
904 * Better AWT focus management fro GTK+ peers.
905 * Much faster and better fonts support
906 (for both gdk Graphics and cairo Graphics2D)
907 * AWT Choice fixes for hidden components.
908 * HTTP Connection Handler fixes for POST support.
909 * Much fuller collection documentation.
910 * Lots of Calendar bug fixes.
911 * More javax.imageio support.
912 * Better AWT Help MenuBar support.
913 * Lookahead support for regular expressions.
914 * Serialization object stream fixes for multiple ClassLoader scenarios.
915 * Swing TabbedPane, ColorChooser and ComboBox improvements.
916 * Start of JTree functionality.
917 * Improved Eclipse 3 support for GNU Classpath based runtimes.
919 Runtime interface Changes:
921 * New --enable-java-lang-system-explicit-initialization configuration
922 option. (Warning, will be replaced in next release, please consult
924 * The reference implementation of VMClassLoader has default
925 implementations for getResource(s) and provides support for a new
926 default getSystemClassLoader implementation.
928 New in release 0.11 (Sep 13, 2004)
930 * javax.swing.Spring and SpringLayout support.
931 * Added pluggable look and feel support for BasicTextFieldUI and
932 BasicToolBarSeparatorUI.
933 * java.swing.text support for (Default and Layered) Highlighter, FieldView,
934 PlainView, TabExpander and TabableView added.
935 * Start of JTable and JTree implementation.
936 * Internal Swing frames work.
937 * JMenu and JPopupMenu work.
938 * New gtk+ AWT FileDialog peer now based on gtk+2.4 or higher.
939 * java.awt.image LookupTables and kernel support.
940 * Improved java.awt.image.BufferedImage support.
941 * AWT 1.0 event model support.
942 * GNU Classpath now comes with some example programs (see examples/README).
943 * New javax.crypto, javax.crypto.interfaces, javax.crypto.spec, javax.net,
944 javax.net.ssl, javax.security.auth, javax.security.auth.callback,
945 javax.security.auth.login, javax.security.auth.x500, javax.security.sasl
946 and org.ietf.jgss packages are now officially part of GNU Classpath.
947 Extra crypto algorithms can be obtained from the GNU Crypto project,
948 a full TLS implementation is provided by the Jessie project.
949 http://www.gnu.org/software/gnu-crypto/
950 http://www.nongnu.org/jessie/
951 * Frame.setIconImage() support.
952 * AWT GDKGraphics scaling.
953 * New configure flag --enable-gtk-cairo to build Graphics2D implementation
954 build on cairo and pangoft2. Enabled at runtime by defining the system
955 property gnu.java.awt.peer.gtk.Graphics=Graphics2D.
956 * javax.swing.JSpinner implemented.
957 * Extensive documentation update for java.util collection classes.
958 * java.awt.geom completed. Area, Arc2D, Ellipse2D and Line2D implemented.
959 * GNU JAXP is no longer included with GNU Classpath. Runtime, compiler and
960 tool integrators are encouraged to directly integrate GNU JAXP.
961 This release has been tested against GNU JAXP 1.1.
962 http://www.gnu.org/software/classpathx/jaxp/jaxp.html
963 * JColorChooser, JComboBox and JTextField implemented, including example
964 uses in GNU Classpath Examples swing Demo.
966 Runtime interface Changes:
968 * java.lang.Compiler now uses the new java.lang.VMCompiler; there is
969 a reference implementation that most VMs can use.
970 * java.lang.VMSystem has a new getenv(String) method and a reference C/JNI
971 implementation that should work on most Posix like systems.
972 * java.util.TimeZone has been split into a platform independent class and
973 a platform dependent class VMTimeZone. GNU Classpath comes with a generic
974 way to get at the default time zone for Posix/GNU-like platforms.
975 * [VM]AccessController improvements. In particular it handles
976 `doPrivileged' calls better, and allows for recursive `doPrivileged'
977 calls in the same Thread. (see vm/reference/java/security/)
979 New in release 0.10 (Jul 9, 2004)
981 * java.net.URL now uses application classloader to load URLStreamHandlers
982 and reuses URLStreamHandlers when URL is reset (but protocol isn't changed).
983 * java.io.File.deleteOnExit() implementation.
984 * java.text multiple new features and bug fixes
985 (only 2 out of the 1000+ java.text Mauve tests now fail).
986 * Better (non-black) default AWT System colors.
987 * AWT lists use GTK treeviews.
988 * Proper AWT focus management has been implemented.
989 * Swing menus and scrollpanes are beginning to work.
990 * Swing splitpanes, dialogs and internal frames were added.
991 * Swing repainting / double buffering was redone.
992 * Font management and Pango DPI conversion fixes.
993 * A lot of AWT imaging and event bugs have been picked out.
994 * More of javax.swing.text has been implemented.
995 * javax.swing.Timer has been reimplemented.
996 * java.security.AccessController has been implemented
997 (see runtime section).
998 * The default java.lang.SecurityManager now uses AccessController.
999 * New java.beans.Statement and Expression implementations.
1000 * Small FileChannel implementation speed improvement for traditional
1002 * Regenerated all included JNI header files with gcjh (3.5 CVS),
1003 removes extra extern modifier and allows stricter compiler warning.
1004 * More C code cleanups (-Wmissing-declarations, -Wmissing-prototypes and
1005 -Wstring-prototypes) and jni.h fixes (a few funtion prototype fixes,
1006 made it compilable with C++ compilers and jni.h got renamed from jni.h.in).
1007 * Double.toString() and Float.toString() now work properly on 64-bit
1009 * PPC Darwin, arm, x86-64 and s/390 JNI C code compilation fixes.
1010 * Build system refactored and removed old Japhar specific support.
1011 * The gnu.java.awt.EmbeddedWindow class has been improved, and now
1012 supports embedding AWT windows in other top-level X windows.
1013 This functionality is required by gcjwebplugin.
1014 * gcjwebplugin, an applet viewer that can be embedded into several web
1015 browsers, has been extensively tested with this release of classpath.
1016 (See http://www.nongnu.org/gcjwebplugin/)
1017 * Runtime environments based on GNU Classpath 0.10 should be able to
1018 start up Eclipse 3.0 out of the box now.
1020 Runtime interface Changes:
1022 * VMProcess.destroy() default implementation fixes.
1023 * Fixed the "portable native sync" code; it had been broken since
1024 Classpath release 0.06, when we upgraded to GTK+2.
1025 Classpath's AWT peers use GTK+. GTK+ uses GLIB. GLIB by default uses
1026 the platform's native threading model -- pthreads in most cases.
1027 If the Java runtime doesn't use the native threading model, then you should
1028 specify --portable-native-sync when configuring Classpath, so that GLIB will
1029 use the Java threading primitives instead. (For a superior alternative,
1031 * The VM can set the system property
1032 gnu.classpath.awt.gtk.portable.native.sync instead of using the
1033 --portable-native-sync configure-type option.
1034 See doc/vmintegration.texinfo for details.
1035 * We intend that the next release of GNU Classpath will require the VM
1036 to provide JNI 1.2. Classpath currently uses only JNI 1.1, except for
1037 one JNI 1.2 function: GetEnv(), in the JNI Invocation API.
1038 If this poses problems, please raise them on the classpath mailing list.
1039 * The reference implementation of VMThread.holdsLock(Object) now has
1040 a default implementation written in java. For efficiency and to
1041 prevent spurious wakeups a real 'native' runtime version can be supplied.
1042 * There is a new java.security.VMAccessController class that runtimes need
1043 to implement to properly support SecurityManagers. The default
1044 implementation that comes with GNU Classpath makes sure that ANY attempt
1045 to access a protected resource is denied when a SecurityManager is
1046 installed. Which is pretty secure, but also no very useful.
1047 Please see the documentation in
1048 vm/reference/java/security/VMAccessController.java,
1049 and please give feedback on the GNU Classpath mailinglist whether or not
1050 the current AccessController framework is flexible enough.
1052 New in release 0.09 (May 2, 2004)
1054 * Includes updated GNU JAXP version from 2004-02-01.
1055 * Native C code is now -ansi -pedantic (C89) clean and (almost) -Wall clean.
1056 * java.io is now implemented by delegating most tasks directly to java.nio.
1057 * Reworked/Optimized implementations of java.nio.Buffer and subclasses.
1058 * New javax.print, javax.print.attribute[.standard] and javax.print.event
1059 packages and classes.
1060 * java.text attributed iterators support.
1061 * New javax.imageio, javax.imageio.event and javax.imageio.spi packages and
1063 * GNU Classpath can now load service providers that are described via
1064 META-INF/services/* resources in extension JARs. This is useful for
1065 implementing the various APIs that are supposed to be extensible via
1066 custom plugins. For details, please see the documentation of
1067 gnu.classpath.ServiceFactory.
1068 Application developers are strongly discouraged from calling glibj
1069 internal packages. Instead, they might want invoke the newly implemented
1070 javax.imageio.spi.ServiceRegistry.lookupProviders, which is a standard
1071 method for loading plug-ins.
1072 * New developers wanting to help the GNU Classpath project might want to
1073 review the greatly expanded Hacker Guide included in the doc directory
1074 or online at http://www.gnu.org/software/classpath/docs/hacking.html
1075 Also the FAQ has been expanded. And when working from CVS you can now use
1076 a simple autogen.sh script to get all autotools magic done automagically.
1077 * New configure option --with-glibj which defines how to install the glibj
1078 class files as zip, as flat directory files or both (zip|flat|both)
1079 [default=zip]. When working with multiple runtimes some of which might
1080 not support bootstrap classes in zip files the --with-glibj=both option
1081 is recommended (this does take extra disc space).
1082 * Two big code drops from the libgcj gui branch updating various java.awt
1083 and javax.swing classes.
1084 * Multiple java.net.InetAdress fixes and java.rmi fixes.
1085 * ServerSocket.accept() now restarts listening when system call interrupted.
1086 * Much cleanups to make standard API doc valid XHTML (not completed yet).
1087 * A scan for unused variables and non-static invocation of static methods
1088 turned up a couple of subtle bugs which have now all been fixed.
1089 * The Mauve testsuite has been cleaned up considerable and lots of issues
1090 in the GNU Classpath core class implementation have been fixed.
1092 VM Interface changes:
1094 * java.lang.Class/VMClass interface was changed. The interface now no
1095 longer requires an instance of VMClass for each Class instance. Instead
1096 the field vmdata in Class is now of type Object.
1097 * GNU Classpath now assumes that JNI calls SetXField can modify final
1098 fields. This was previously used silently for System.in/out/err and should
1099 be considered as a feature now.
1100 * A new VMProcess and a sample JNI C implementation are now provided to
1101 make Runtime.exec() work out of the box on some systems. This requires
1102 a small change to VMRuntime.exec() when a runtime wants to use it as the
1103 default java.lang.Process implementation.
1104 * The implementation of most of java.io through java.nio moved serveral
1105 runtime specific I/O methods. Most methods do have a generic default native
1106 C JNI implementation in native/jni/java-nio.
1107 * Runtime support methods for java.io.File have been moved to VMFile which
1108 also comes with a default JNI C implementation.
1109 * To support the new service provider mechanism runtimes must make sure that
1110 extension JARs are made accessible via the default context class loader.
1112 New in release 0.08 (2004/12/03)
1114 * java.util.regexp implementation through gnu.regexp wrappers.
1115 * java.net.URI implementation.
1116 * Working implementation of javax.swing.undo.
1117 * java.awt.geom.CubicCurve2D/QuadCurve2D: Can now solve cubic and quadratic
1118 equations; implementation adapted from the GNU Scientific Library.
1119 * Lots of java.awt and gtk+ peer improvements. Also more Swing work. Start
1120 of EmbeddedWindow support.
1121 * BufferedReader speed improvements.
1122 * Improved useabilty of java.text implementation for several applications.
1123 * ObjectInputStream is much faster and more compatible with other
1125 * Fix handling of alias methods, where a method has been deprecated in
1126 favour of a new one with the same funtion but a different name.
1127 (See Deprecated Methods section in the GNU Classpath Hacking Guide.)
1128 * javax.print.attribute.standard added.
1129 * Lots of java.nio, java.net, java.io
1130 * Depend on autoconf 2.59+ and automake 1.7+, GCJ 3.3+, jikes 1.18+.
1132 VM Interface changes:
1133 * Split native methods in java.lang.Runtime into java.lang.VMRuntime.
1134 * Resources are now also loaded/needed through the bootstrap classloader
1135 (gnu.regexp needs MessageBundle included in glibj.zip
1137 Fixed Classpath bugs:
1138 #6095 java.awt.geom.QuadCurve2D.solveQuadratic sometimes gives
1140 #7099 EventListenerList.getListenerCount should accept null argument
1141 #7104 EventListenerList.add does not work
1142 #7105 EventListenerList.remove does not work
1143 #7107 DefaultBoundedRangeModel.setValue and friends should not throw
1146 New in release 0.07 (2003/30/11)
1148 * Works with libtool 1.5 (and 1.4.3).
1149 * java.awt gtk+ peers now depend on gtk+ 2.2.x and uses pango.
1150 Lots and lots improvements on the peers.
1151 * java.awt.geom.CubicCurve2D, java.awt.geom.QuadCurve2D:
1152 Subdivision and flatness calculation implemented.
1153 * java.awt.geom.FlatteningPathIterator: Working implementation.
1154 * gnu.java.awt.BitwiseXORComposite helper class.
1155 * New rmic compilers (jikes, kjc) support.
1156 * java.text bug fixing and 1.4 updates (Currency).
1157 * Hashtable and HashMap function more similar to other implementations.
1158 * javax.naming and java.beans classloader fixes.
1159 * URL parsing, URLConnection, protocol and (needed) permission fixes.
1160 * More java.nio implementation
1161 (API complete, but implementation not finished yet).
1162 * Lots of java.net code cleanup.
1163 * Improved documentation.
1164 * Numerous bug fixes in almost every package, and lots of updates for
1166 * Fixed Classpath bugs:
1167 #2944 Incorrect synchronization in java.util.logging.ErrorManager
1168 #6075 java.awt.geom.GeneralPath.getCurrentPoint returns wrong results
1169 #6076 java.awt.geom.GeneralPath constructor sometimes hangs
1170 #6089 java.awt.geom.GeneralPath.getPathIterator does not work
1173 VM Interface changes:
1175 * Thread has been split in a VM-independent Thread class and a VM-dependent
1178 New in release 0.06 (2003/22/08)
1180 * Update java.awt peers to GTK+2.
1181 * java.awt.GridBagLayout implementation.
1182 * javax.swing.border implementation.
1183 * java.security and java.security.cert updated to 1.4 spec.
1184 * New JNI native target code layer. See native/target/readme.txt.
1185 * --enable-regen-headers configure flag for automatic jni .h file generation.
1186 * Removed workaround for gcj 3.2 and lower, gcj 3.3+ or jikes 1.18+ is now
1187 needed for compiling.
1188 * Lots of improvements and/or new classes for java.awt, java.awt.dnd,
1189 java.awt.font, java.awt.geom, java.awt.image, java.io, java.math, java.net,
1190 java.nio, java.rmi, java.text, java.util, javax.swing, javax.swing.plaf,
1193 VM Interface changes:
1195 * VMClassLoader.loadClass(), the bootstrap classloader called by
1196 Class.forName() and ClassLoader.loadClass(), may now return null when
1197 a class is not found instead of throwing a new ClassNotFoundException.
1198 This is a performance optimization in some cases. This also changes
1199 the Class.forName() reference code.
1200 * Native methods in Class have been moved to VMClass. A few additional
1201 methods are also available in VMClass to provide optional performance
1203 * A VM can now supply its own String.intern() strategy through the
1204 VMString class. The supplied VMString reference class implements the
1205 original WeakHashMap strategy.
1206 * Float and Double to/from bits conversion functions can now be supplied by
1207 the VM through VMFloat and VMDouble. Default JNI conversion methods are
1210 New in release 0.05 (2003/02/15)
1211 * Supports free Java VMs Jikes RVM and Kissme out of the box, perhaps others.
1212 * Supports GNU Crypto 1.1 as the official provider of cryptographic primitives
1213 and tools for GNU Classpath, available separately from
1214 http://www.gnu.org/software/classpathx/crypto/crypto.html.
1215 * Supports GNU Classpath Tools sub-project of GNU Classpath, official provider
1216 of standard tools such as gjdoc, a javadoc replacement, and others. Future
1217 releases of GNU Classpath will begin to include these tools, available
1218 separately from http://www.gnu.org/software/cp-tools/.
1219 * Java primitives can be used to support AWT native threading, see
1220 the --enable-portable-native-sync configure option which may become the
1221 default in a future release.
1222 * Include file jni.h has been updated to the 1.4 specification.
1223 * VM specific internal types for jobject, jfieldID, and jmethodID are
1224 supported in jni.h. More details can be found by reading the comment
1225 in include/jni.h.in. By default the old definitions are used instead.
1226 * New VM helper class java.io.VMObjectStreamClass which should provide
1227 the hasClassInitializer() method. Previously ObjectStreamClass used
1228 Class.getDeclaredMethod("<clinit>") but according to the spec this
1229 should always throw NoSuchMethodException for class initialization methods.
1230 A JNI reference implementation is provided as
1231 vm/reference/java-io/java_io_VMObjectStreamClass.c
1232 * There have been numerous infrastructure improvements
1233 * Configure option --enable-gjdoc to generate javadoc-like output
1234 * Gjdoc output is included with distribution, see doc/api/html/
1235 * DESTDIR fully supported for install and uninstall
1236 * Runtime.execInternal contract changed to allow for null `env'
1237 and to accept `dir' argument.
1238 * VMObject.getClass() removed. It was never used.
1239 * java.lang.Throwable is now a 'normal' GNU Classpath class that uses the
1240 VM specific java.lang.VMThrowable to get at the VM state and (if needed)
1241 the StackTraceElements for a particular exception. A default implementation
1242 (that does nothing) is provided in vm/reference/java/lang/VMThrowable.java.
1243 * The vm/reference classes from the gnu.vm.stack and their counterparts
1244 ExecutionStack and StackFrame in gnu.java.lang have been removed since they
1245 are not actually part of the VM interface anyway.
1246 * The GPLed com.sun.javadoc classes have been moved to the gjdoc application
1247 from the GNU Classpath Tools project. See for more information the homepage
1248 at: <http://www.gnu.org/software/cp-tools/>.
1250 New in release 0.04 (2002/05/05)
1251 * Additional configure options to disable zip creation and installation as
1252 well as disable gtk peer native compilation.
1253 * Addition of java.nio, java.util.logging, and javax.swing.
1254 * Integration of most or all of the ORP patches to date, the purpose of
1255 which are to make it possible to use JBOSS with ORP and Classpath. This
1256 is still in a testing phase however.
1257 * Significant changes in the reference VM interface that may require
1258 support from the JVMs.
1261 New in release 0.03 (2002/02/08)
1262 * More merges with libgcj have been performed including java.math which now
1263 provides a pure Java implementation of that package.
1264 Current status at <http://gcc.gnu.org/java/libgcj-classpath-compare.html>
1265 * A pure Java implementation (Jazzlib) of java.util.zip is available.
1266 * Added the java.rmi implementation that Transvirtual donated to the FSF.
1267 * Includes jni.h now, eliminating the need to specify a particular VM
1269 * No proprietary classes or programs are required to compile.
1270 Compiles out of the box with jikes or gcj.
1271 * Separation of compiling Java source and native libraries through the
1272 configure mechanism. If given no arguments, configure will setup the
1273 subsequent build to only produce Java bytecode (.class files). More
1274 information is available in INSTALLING.
1275 * Support for compiling in a separate directory, as an example you may
1276 cd classpath-0.03; mkdir build; cd build; ../configure; make
1277 * Works with Orp 1.0.9 out of the box. Build instructions can be found at
1278 <http://www.gnu.org/software/classpath/doc/orp.html>
1279 * Lots of bugfixes that were found by using Classpath with the gcj, Orp,
1280 SableVM, KissMe and Jaos VMs. Please use our bugdatabase at
1281 <http://savannah.gnu.org/support/?group_id=85>
1282 * Lots of updates to make Classpath more compliant with the 1.2, 1.3 and 1.4
1283 API specification. The current status can be found at
1284 <http://www.gnu.org/software/classpath/status.html>
1285 * All files are now distributed under the same terms. Added clarification to
1288 New in release 0.02 (2001/01/06)
1289 * Support for printing exceptions with Japhar 0.09 + patch included in
1290 resource/japhar-0.09.patch.1.
1291 * Typos, assorted bugfixes.
1293 New in release 0.01 (2000/11/20)
1294 * More packages are included now, though many remain untested.
1295 * Support for Japhar 0.09 included.
1297 New in release 0.00 (1999/02/01)
1298 * First official development release of clean room class library for Java
1299 * Following packages included:
1303 -- java.lang.reflect
1306 -- java.security (partial and non-functioning)
1307 -- java.security.acl
1308 -- java.security.interfaces
1310 * Code is mostly Java 2 (see JDK 1.2) compatible with some functionality
1311 missing and/or untested.
1312 * Support for Japhar (http://www.japhar.org/) virtual machine is included.
1313 Requires the current Japhar from CVS.
1314 * Extensive javadoc comments for public API included
1315 * Licensed under the GNU Library General Public License (see COPYING.LIB)
1316 * Does not depend on any non-free code - developed in a "clean room"
