GNU Classpath 0.91 "All for One, One for All" 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): RMI activation daemon and persistent naming service tools are now included. Print service discovery, single document print jobs and support for client-formatted print data through CUPS has been added. Support for custom mouse cursors, system clipboard and selection access has been implemented. A Free Swing OceanTheme and support for assistive technologies (accessibility) has been added. The VM runtime interface has been merged with the generics version to support annotations and other 1.5 language features. GNU Classpath 0.91 does not yet support all new 1.5 additions, but there is also an experimental GNU Classpath "generics" release. classpath-0.91-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 can use it 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. 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 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 more than 45.000 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 44975 out of 45537 Mauve core library tests. Conformance reports for the included jaxp support can be found in the doc/README.jaxp file.

Currently supported features from the Java Print Service API are print service discovery (CUPS registered printers), single document print jobs and support for client-formatted print data. An example application (see: examples/gnu/classpath/examples/print/Demo) has been added to show the API usage for service discovery and printing of files. * The GTKToolkit now gives access to the both the system clipboard and system selection. * Custom mouse cursor support has been added to the gtk+ peers. And cursors can now also be set on light-weight components. * Free Swing improvements: Support for OceanTheme has been mostly completed and turned on as default Metal theme. X11-style Copy and Paste behavior in text components with the middle mouse button. Support cursor changes on various components when resizing. Support for Look and Feel window decorations has been added. * Updated locale data information to CLDR 1.3. * Various bugs in Classpath's SecureRandom implementations have been fixed; that class now respects the "securerandom.source" security property and the "java.security.egd" system property. * Support for assistive technologies has been added to AWT and Swing. Runtime interface changes: * A new class, VMArray, is now available which separates the native array creation method from java.lang.reflect.Array. * A new class, gnu.classpath.Unsafe, is provided for handling the new low-level operations required by java.util.concurrent. * The reference implementations of Method, Constructor, and Field now have a new native getModifiersInternal() method. The public getModifiers() method in each case has been rewritten in terms of this method. * The reference implementation of VMThread has been updated to handle the new Thread.UncaughtExceptionHandler support. * A new class, java.security.VMSecureRandom, is now available that is used to generate random numbers for seeding cryptographically-secure pseudo-random number generators. * VMClass and the reference implementations of Method, Constructor and Field now include a number of 1.5 methods imported from the generics branch. These are all optional (in the sense that the methods associated with them merely fail on use if the VM doesn't provide them, rather than the VM failing altogether), but VMs should aim to support them where possible. * The implementation of java.lang.instrument has been merged to the main branch from the generics branch. * The VM interfaces of the main branch and the generics branch are now consistent with one another. As a result, the main branch includes an additional environ() function in VMSystem and an additional argument has been added to nativeSpawn() in VMProcess. * Annotation support is now available in the main branch, if the VM supports it. The VM should implement VMClass.getDeclaredAnnotations, Constructor.getAnnotation, Constructor.getDeclaredAnnotations, Field.getAnnotation, Field.getDeclaredAnnotations, Method.getAnnotation and Method.getDeclaredAnnotations. * java.lang.Package now has a new constructor that takes the defining ClassLoader as an extra argument. If you use a custom version of VMClassLoader, please switch it to use this constructor. * The reference implementation of VMClassLoader.getBootPackages() now reads the META-INF/INDEX.LIST resource using the java.boot.class.path system property. 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.
