GNU Classpath "95% and counting" 0.19 released
|
| 17 |
|
|
|
| 18 |
|
|
GNU Classpath, essential libraries for java, is a project to create
|
| 19 |
|
|
free core class libraries for use with runtimes, compilers and tools
|
| 20 |
|
|
for the java programming language.
|
| 21 |
|
|
|
| 22 |
|
|
The GNU Classpath developer snapshot releases are not directly aimed
|
| 23 |
|
|
at the end user but are meant to be integrated into larger development
|
| 24 |
|
|
platforms. For example the GCC (gcj) and Kaffe projects will use the
|
| 25 |
|
|
developer snapshots as a base for future versions.
|
| 26 |
|
|
|
| 27 |
|
|
Some highlights of changes in this release (more extensive list below):
|
| 28 |
|
|
|
| 29 |
|
|
Much more efficient painting for large Free Swing GUIs. Improved
|
| 30 |
|
|
accessibility support. HttpURLConnection rewrite. Official CORBA
|
| 31 |
|
|
VMCID assigned. Start of RMI over IIOP support. Qt4 support for
|
| 32 |
|
|
OS-X. Much improved Free Swing Metal theme. Free Swing Demo includes
|
| 33 |
|
|
theme switcher example (Metal, Ocean, GNU). JBoss now starts up and
|
| 34 |
|
|
Jonas testsuite passes for 95%. Support for the javax.sound.midi
|
| 35 |
|
|
framework and experimental DSSI and ALSA service providers. Early
|
| 36 |
|
|
version of the popular StAX API. Now has 96% coverage of 1.4 API.
|
| 37 |
|
|
|
| 38 |
|
|
This is the first time we also have a pre-release of our 1.5 generics
|
| 39 |
|
|
work. classpath-0.19-generics contains a version of the core library
|
| 40 |
|
|
that uses the new 1.5 language features such as generics and
|
| 41 |
|
|
enumerations. ECJ and JamVM are known to support the generics release
|
| 42 |
|
|
out of the box. And you should be able to run Eclipse 3.1 with it to
|
| 43 |
|
|
develop programs that use the new 1.5 language and core library
|
| 44 |
|
|
additions. classpath-generics is a work in progress and not as
|
| 45 |
|
|
extensively tested as our regular releases. But please try it out if
|
| 46 |
|
|
you want to help us test the new 1.5 support of the core libraries.
|
| 47 |
|
|
|
| 48 |
|
|
For this release we setup a Free Swing Test Application page
|
| 49 |
|
|
http://developer.classpath.org/mediation/FreeSwingTestApps
|
| 50 |
|
|
Please see that page for showcases of applications that work with this
|
| 51 |
|
|
release and to help test other applications.
|
| 52 |
|
|
|
| 53 |
|
|
It is also the first release that has GNU Classpath promotion banners.
|
| 54 |
|
|
http://developer.classpath.org/mediation/ClasspathBanners
|
| 55 |
|
|
Please feel free to add them to your project pages if your project is
|
| 56 |
|
|
known to work with GNU Classpath or just to promote the project.

|

|
|
This release depends on gtk+ 2.4 for AWT support. But gtk+ 2.6 or
|
| 69 |
|
|
higher is recommended. Included, but not activated by default in this
|
| 70 |
|
|
release is a Graphics2D implementation based on the Cairo Graphics
|
| 71 |
|
|
framework (http://www.cairographics.org). Enabling this makes programs
|
| 72 |
|
|
like JFreeChart and JEdit start up on GNU Classpath based runtimes.
|
| 73 |
|
|
To enable this support install the cairo 0.5.x snapshot, configure GNU
|
| 74 |
|
|
Classpath with --enable-gtk-cairo.
|
| 75 |
|
|
|
| 76 |
|
|
One of the major focuses of the GNU Classpath project is expanding and
|
| 77 |
|
|
using the Mauve test suite for Compatibility, Completeness and
|
| 78 |
|
|
Correctness checking. Various groups around GNU Classpath collaborate
|
| 79 |
|
|
on the free software Mauve test suite which contains around 34.000
|
| 80 |
|
|
core library tests. Mauve has various modules for testing core class
|
| 81 |
|
|
library implementations, byte code verifiers, source to byte code and
|
| 82 |
|
|
native code compiler tests. Mauve also contains the Wonka visual test
|
| 83 |
|
|
suite and the Jacks Compiler Killer Suite.
|
| 84 |
|
|
See for more information: http://www.sourceware.org/mauve/
|
| 85 |
|
|
This release passes 33.381 out of 34.262 Mauve core library tests.

New in release 0.19 (Nov 2, 2005)
|
| 114 |
|
|
(See the ChangeLog file for a full list of changes.)
|
| 115 |
|
|
|
| 116 |
|
|
* The Swing RepaintManager has been reworked for more efficient
|
| 117 |
|
|
painting, especially for large GUIs.
|
| 118 |
|
|
|
| 119 |
|
|
* The Swing layout manager OverlayLayout has been implemented, the
|
| 120 |
|
|
BoxLayout has been rewritten to make use of the SizeRequirements
|
| 121 |
|
|
utility class and caching for more efficient layout.
|
| 122 |
|
|
|
| 123 |
|
|
* Improved accessibility support for Swing.
|
| 124 |
|
|
|
| 125 |
|
|
* The java.net.HttpURLConnection implementation no longer buffers the
|
| 126 |
|
|
entire response body in memory. This means that response bodies
|
| 127 |
|
|
larger than available memory can now be handled.
|
| 128 |
|
|
|
| 129 |
|
|
* The Andrew Watson, Vice President and Technical Director of the
|
| 130 |
|
|
Object Management Group, has officially assigned us 20 bit Vendor
|
| 131 |
|
|
Minor Code Id: 0x47430 ("GC") that will mark remote Classpath -
|
| 132 |
|
|
specific system exceptions. Obtaining the VMCID means that GNU
|
| 133 |
|
|
Classpath now is a recogniseable type of node in a highly
|
| 134 |
|
|
interoperable CORBA world.
|
| 135 |
|
|
|
| 136 |
|
|
* Classpath now includes the first working draft to support the RMI
|
| 137 |
|
|
over IIOP protocol. The current implementation is capable for remote
|
| 138 |
|
|
invocations, transferring various Serializables and Externalizables
|
| 139 |
|
|
via RMI-IIOP protocol. It can flatten graphs and, at least for the
|
| 140 |
|
|
simple cases, is interoperable with Sun's jdk 1.5.
|
| 141 |
|
|
|
| 142 |
|
|
* Qt4 configury switches for OS-X. Additional to the --enable-qt-peer,
|
| 143 |
|
|
OS-X users with a Qt4 installation can build the qt-peers with the
|
| 144 |
|
|
argument --with-qt4dir=.
|
| 145 |
|
|
|
| 146 |
|
|
* Significant progress has been made in the implementation of the
|
| 147 |
|
|
javax.swing.plaf.metal.* package, with most UI delegates in a
|
| 148 |
|
|
working state now. Please test this with your own applications and
|
| 149 |
|
|
provide feedback that will help us to improve this package.
|
| 150 |
|
|
|
| 151 |
|
|
* The GUI demo (gnu.classpath.examples.swing.Demo) has been extended
|
| 152 |
|
|
to highlight various features in our free-swing implementation. And
|
| 153 |
|
|
includes a look and feel switcher (Metal default, Ocean or GNU).
|
| 154 |
|
|
|
| 155 |
|
|
Runtime interface changes:
|
| 156 |
|
|
|
| 157 |
|
|
* Changed implementation of VMClassLoader.getPackage(s) : new method
|
| 158 |
|
|
VMClassLoader.getBootPackages should be implemented by the vm, and
|
| 159 |
|
|
sould return a string array of boot package names ("java.lang",
|
| 160 |
|
|
"java.net", ...). Feedback from vm implementors for usability and
|
| 161 |
|
|
relevance of the getBootPackages method would be greatly
|
| 162 |
|
|
appreciated.
|
| 163 |
|
|
|
| 164 |
|
|
New Untested/Disabled Features:
|
| 165 |
|
|
|
| 166 |
|
|
The following new features are included, but not ready for
|
| 167 |
|
|
production yet. They are explicitly disabled and not supported. But
|
| 168 |
|
|
if you want to help with the development of these new features we
|
| 169 |
|
|
are interested in feedback. You will have to explicitly enable them
|
| 170 |
|
|
to try them out (and they will most likely contain bugs). If you are
|
| 171 |
|
|
interested in any of these then please join the mailing-list and
|
| 172 |
|
|
follow development in CVS.
|
| 173 |
|
|
|
| 174 |
|
|
* Cairo Gtk+ Graphics2D support, enabled by giving configure
|
| 175 |
|
|
--enable-gtk-cairo.
|
| 176 |
|
|
* QT4 AWT peers, enable by giving configure --enable-qt-peer.
