Silence a javadoc diagnostic with Eclipse 3.4
The FilteredCheckboxTree.getRefreshJobDelay method overrides
a method in Eclipse 3.5, which means it does not require
a javadoc. The project settings reflects and enforces this,
which does not work with Eclipse 3.4 since getRefreshJobDelay
is a new method there and the compiler flags this as an error.
Since this is the only place where this is a problem we create
a javadoc comment instead of relaxing the rules.
