GNU Classpath 0.20 released GNU Classpath, essential libraries for java, is a project to create free core class libraries for use with runtimes, compilers and tools for the java programming language. The GNU Classpath developer snapshot releases are not directly aimed at the end user but are meant to be integrated into larger development platforms. For example the GCC (gcj) and Kaffe projects will use the developer snapshots as a base for future versions. More projects based on GNU Classpath: http://www.gnu.org/software/classpath/stories.html Some highlights of changes in this release (more extensive list below): New StAX pull parser and SAX-over-StAX driver. Full XMLEncoder implementation. The packages javax.sound.sampled, javax.print.attribute and javax.print.event have been implemented. Lots of new datatransfer, print, swing and swing.text work. Performance improvements in the painting/layout mechanism. Additional 1.5 support, including (separate) generic branch release. SecurityManager cleanups and start of review of all Permission checks. Buildable on cygwin. Fully buildable as "in-workspace" library-plus-vm inside (native) Eclipse. Real world Free Swing and CORBA example added. GNU Classpath 0.20 also comes in a "generic" version. classpath-0.20-generics contains a version of the core library that uses the new 1.5 language features such as generics and enumerations. ECJ, JamVM, IKVM and Cacao are known to support the generics release (*). And you should be able to run Eclipse 3.1 with it to develop programs that use the new 1.5 language and core library additions. classpath-generics is a work in progress and not as extensively tested as our regular releases. But please try it out if you want to help us test the new 1.5 support of the core libraries. (*) There is one additional VM interface needed for the VMClassLoader static final Class defineClassWithTransformers(ClassLoader loader, String name, byte data, int offset, int len, ProtectionDomain pd) Which is used for the new java.management.instrumentation support. See the VM Integration Guide for more details: http://www.gnu.org/software/classpath/docs/vmintegration.html Thanks to a donation of Berkeley Signal Inc GNU Classpath now has an official autobuilder machine which is used for quality assurance, regression testing, conformance reports and for publishing continous snapshots. The machine can be reached as http://builder.classpath.org/ 40 people actively contributed to this release and made 605 CVS commits during the last two months of development (excluding the generics branch work). diffstat since 0.19: 617 files changed, 89622 insertions(+), 37478 deletions(-) More details about the various changes and contributions below. A full list of bug reports fixed for this release can be found at: http://gcc.gnu.org/bugzilla/buglist.cgi?product=classpath&target_milestone=0.20 The GNU Classpath developers site http://developer.classpath.org/ provides detailed information on how to start with helping the GNU Classpath project and gives an overview of the core class library packages currently provided. For each snapshot release generated documentation is provided through the GNU Classpath Tools gjdoc project. A documentation generation framework for java source files used by the GNU project. Full documentation on the currently implementated packages and classes can be found at: http://developer.classpath.org/doc/ For more information about the project see also: - GNU Classpath home page: http://www.gnu.org/software/classpath/ - Developer information (wiki): http://developer.classpath.org/ - Full class documentation http://developer.classpath.org/doc/ - GNU Classpath hackers: http://planet.classpath.org/ - Autobuilder, current build status, build snapshots: http://builder.classpath.org/ - Application test pages (wiki) http://developer.classpath.org/mediation/FreeAWTTestApps http://developer.classpath.org/mediation/FreeSwingTestApps http://developer.classpath.org/mediation/FreeSWTTestApps - GNU Classpath hacking with Eclipse (wiki) http://developer.classpath.org/mediation/ClasspathHackingWithEclipse - GNU Classpath promotion banners: http://developer.classpath.org/mediation/ClasspathBanners - GNU Classpath and Friends meeting (Feb 25/26, Brussels, Fosdem): http://www.gnu.org/software/classpath/events/fosdem06.html This release depends on gtk+ 2.4 for AWT support. But gtk+ 2.6 or higher is recommended. Included, but not activated by default in this release is a Graphics2D implementation based on the Cairo Graphics framework (http://www.cairographics.org). Enabling this makes programs like JFreeChart and JEdit start up on GNU Classpath based runtimes. To enable this support install the cairo 0.5.x snapshot, configure GNU Classpath with --enable-gtk-cairo. One of the major focuses of the GNU Classpath project is expanding and using the Mauve test suite for Compatibility, Completeness and Correctness checking. Various groups around GNU Classpath collaborate on the free software Mauve test suite which contains around 36.000 core library tests. Mauve has various modules for testing core class library implementations, byte code verifiers, source to byte code and native code compiler tests. Mauve also contains the Wonka visual test suite and the Jacks Compiler Killer Suite. See for more information: http://www.sourceware.org/mauve/ This release passes 35534 out of 36255 Mauve core library tests. Conformance reports for the included jaxp support can be found in the doc/README.jaxp file.

Lots of DOM, SAX/StAX, XPath and XSLT improvements. Support for XInclude and XML Base added. Conformance is now regularly tested against various test-suites at http://builder.classpath.org/xml/ See also doc/README.jaxp. * Full beans XMLEncoder implementation. * javax.sound.sampled implementation. * javax.print.attribute and javax.print.event implementated. * Lots of new datatransfer, print swing and swing.text work and optimization. * Additional 1.5 support. Including new (separate) generic branch release. * SecurityManager cleanups and start of review of all Permission checks (includes adding lots of new checks to the Mauve test-suite). * Buildable on cygwin. * Fully buildable as "in-workspace" library-plus-vm inside (native) Eclipse see http://developer.classpath.org/mediation/ClasspathHackingWithEclipse * Full example that shows a real world CORBA and Free Swing implementation. See examples/gnu/classpath/examples/CORBA/swing/README.html Runtime interface changes: * New method VMStackWalker.getClassLoader() was added to avoid an infinite loop between getCallingClassLoader() and Class.getClassLoader(). * The included fdlibm implementation has seen several cleanups to handle new architectures and namespacing issues (in particular for ppc, darwin and non-C99 compilers). Please double check any arithmetic test against new platforms/runtimes. * The gnu.java.net.Plain[Datagram]Socket implementations have been turned into VM reference classes with JNI/Posix implementations. New/Untested/Disabled Features: The following new features are included, but not ready for production yet. They are explicitly disabled and not supported. But if you want to help with the development of these new features we are interested in feedback. You will have to explicitly enable them to try them out (and they will most likely contain bugs). If you are interested in any of these then please join the mailing-list and follow development in CVS. * Cairo Gtk+ Graphics2D support, enabled by giving configure --enable-gtk-cairo. * QT4 AWT peers, enable by giving configure --enable-qt-peer.
