  15 <pre>
  16 We are pleased to announce a new development release of GNU Classpath.
  17
  18 GNU Classpath, Essential Libraries for Java, is a project to create free
  19 core class libraries for use with virtual machines and compilers for the
  20 java programming language.
  21
  22 GNU Classpath 0.10 can be downloaded from
  23 ftp://ftp.gnu.org/pub/gnu/classpath/
  24 or one of the ftp.gnu.org mirrors
  25 http://www.gnu.org/order/ftp.html

  30 New in release 0.10 (Jul 9, 2004)
  31
  32 * java.net.URL now uses application classloader to load URLStreamHandlers
  33   and reuses URLStreamHandlers when URL is reset (but protocol isn't changed).
  34 * java.io.File.deleteOnExit() implementation.
  35 * java.text multiple new features and bug fixes
  36   (only 2 out of the 1000+ java.text Mauve tests now fail).
  37 * Better (non-black) default AWT System colors.
  38 * AWT lists use GTK treeviews.
  39 * Proper AWT focus management has been implemented.
  40 * Swing menus and scrollpanes are beginning to work.
  41 * Swing splitpanes, dialogs and internal frames were added.
  42 * Swing repainting / double buffering was redone.
  43 * Font management and Pango DPI conversion fixes.
  44 * A lot of AWT imaging and event bugs have been picked out.
  45 * More of javax.swing.text has been implemented.
  46 * javax.swing.Timer has been reimplemented.
  47 * java.security.AccessController has been implemented
  48   (see runtime section).
  49 * The default java.lang.SecurityManager now uses AccessController.
  50 * New java.beans.Statement and Expression implementations.
  51 * Small FileChannel implementation speed improvement for traditional
  52   JNI based systems.
  53 * Regenerated all included JNI header files with gcjh (3.5 CVS),
  54   removes extra extern modifier and allows stricter compiler warning.
  55 * More C code cleanups (-Wmissing-declarations, -Wmissing-prototypes and
  56   -Wstring-prototypes) and jni.h fixes (a few funtion prototype fixes,
  57   made it compilable with C++ compilers and jni.h got renamed from jni.h.in).
  58 * Double.toString() and Float.toString() now work properly on 64-bit
  59   PowerPC systems.
  60 * PPC Darwin, arm, x86-64 and s/390 JNI C code compilation fixes.
  61 * Build system refactored and removed old Japhar specific support.
  62 * The gnu.java.awt.EmbeddedWindow class has been improved, and now
  63   supports embedding AWT windows in other top-level X windows.
  64   This functionality is required by gcjwebplugin.
  65 * gcjwebplugin, an applet viewer that can be embedded into several web
  66   browsers, has been extensively tested with this release of classpath.
  67   (See http://www.nongnu.org/gcjwebplugin/)
  68 * Runtime environments based on GNU Classpath 0.10 should be able to
  69   start up Eclipse 3.0 out of the box now.
  70
  71 Runtime interface Changes:
  72
  73 * VMProcess.destroy() default implementation fixes.
  74 * Fixed the "portable native sync" code; it had been broken since
  75   Classpath release 0.06, when we upgraded to GTK+2.
  76   Classpath's AWT peers use GTK+.  GTK+ uses GLIB.  GLIB by default uses
  77   the platform's native threading model -- pthreads in most cases.
  78   If the Java runtime doesn't use the native threading model, then you should
  79   specify --portable-native-sync when configuring Classpath, so that GLIB will
  80   use the Java threading primitives instead.  (For a superior alternative,
  81   see below.)
  82 * The VM can set the system property
  83   gnu.classpath.awt.gtk.portable.native.sync instead of using the
  84   --portable-native-sync configure-type option.
  85   See doc/vmintegration.texinfo for details.
  86 * We intend that the next release of GNU Classpath will require the VM
  87   to provide JNI 1.2.  Classpath currently uses only JNI 1.1, except for
  88   one JNI 1.2 function: GetEnv(), in the JNI Invocation API.
  89   If this poses problems, please raise them on the classpath mailing list.
  90 * The reference implementation of VMThread.holdsLock(Object) now has
  91   a default implementation written in java. For efficiency and to
  92   prevent spurious wakeups a real 'native' runtime version can be supplied.
  93 * There is a new java.security.VMAccessController class that runtimes need
  94   to implement to properly support SecurityManagers. The default
  95   implementation that comes with GNU Classpath makes sure that ANY attempt
  96   to access a protected resource is denied when a SecurityManager is
  97   installed. Which is pretty secure, but also no very useful.
  98   Please see the documentation in
  99   vm/reference/java/security/VMAccessController.java,
 100   and please give feedback on the GNU Classpath mailinglist whether or not
 101   the current AccessController framework is flexible enough.
 102
 103 Here are answers to some questions you might have about this project and
 104 this release.
 105
 106 1). What is required to build/install/run?
 107
 108 GNU Classpath requires a working GNU build environment and a byte code
 109 compiler such as jikes, gcj or kjc. When creating native code you will
 110 also need a working C compiler and up to date Gnome development
 111 libraries (gtk+, libart and gdk-pixbuf). More information on the
 112 precise version numbers for the tools and libraries can be found in
 113 the INSTALL file.
 114
 115 You will also need a runtime environment. The following environments
 116 have been tested to work out of the box with this release:
 117
 118     * JamVM         (http://jamvm.sourceforge.net/)
 119     * Jikes RVM     (http://www.ibm.com/developerworks/oss/jikesrvm/)
 120     * Kissme        (http://kissme.sourceforge.net/)
 121
 122 For other environments that might need modified version of the current
 123 release see the README file.  A complete list of virtual machines and
 124 compilers known to be based on GNU Classpath can be found at our
 125 website: http://www.gnu.org/software/classpath/stories.html
 126
 127 2). What platforms are supported?
 128
 129 GNU/Linux is the only platform that has been tested.
 130 We plan to eventually support many others.
 131
 132 3). Who should use this software?
 133
 134 Although GNU Classpath is already capable of supporting many
 135 applications written in the java programming language, this is a
 136 development release. As such, there are still some unfinished
 137 components, and some problems are to be expected. You should install it
 138 if you are interested in GNU Classpath development or reporting bugs.
 139 We appreciate both.
 140
 141 For end users we recommend to use one of the development environments
 142 based on GNU Classpath which combine the core libraries with compilers
 143 and other tools needed for creating applications and libraries.
 144
 145     * GCC with GCJ  (http://gcc.gnu.org/java/)
 146     * Kaffe         (http://www.kaffe.org/)
 147
 148 4). Where do I go for more information?
 149
 150 The project home page with information on our mailing list can be
 151 found http://www.gnu.org/software/classpath/.
 152
 153 A good overview of the current status can be found on the GNU Classpath
 154 at FOSDEM'04 page which describes the last GNU Classpath hacker meeting.
 155 It includes reports and presentations on the current status and future
 156 plans: http://www.gnu.org/software/classpath/events/fosdem04.html
