I am running into ssl errors when I try to connect to Gmail server. Looking at the web, this person, http://gcc.gnu.org/ml/java/2007-11/msg00004.html, had similar error and he was told that cacerts would have to be imported for his system via the import-cacerts.sh script. I have found this script in the classpath source archive that I downloaded. I tried running this script with the command: sh import-cacerts.sh But I get this error: import-cacerts.sh: 3: Syntax error: "(" unexpected How do I import this cacerts correctly? Forgive me - I am new to this! Thanks! Regards Donal </pre> Donal Geoghegan 2012-04-27T12:05:18 http://comments.gmane.org/gmane.comp.java.classpath.devel/10344 <pre>Hi there. I want to reanimate a discussion from 2007 [1,2] about the Assertion/System Assertion handling. As far as I know GNU Classpath can't distinguish between normal assertions (-ea/-eanableassertions) and assertions for system classes (-esa/-enablesystemassertions, i.e. classes with no classloader [3]). The only interface for the VM is the method VMClassLoader.defaultAssertionStatus(). It is not clear if this is supposed to return the system assertion status or the normal assertion status (vm integration doc [4] vs. javadoc [5]). On the one hand, it is used to set the defaultAssertionStatus for java.lang.ClassLoader [6] which would imply that it is the normal assertion status. On the other hand, the very same flag is used for setting the assertion status for system class in java.lang.Class (desiredAssertionStatus)[7]. I think we need two dedicated methods in VMClassLoader. getDefaultAssertionStatus() for normal assertions (i.e. -ea) and getDefaultSystemAssertionStatus() for system assertions (i.e. -esa). ClassLoader should use VMClassLoader.getDefaultAssertionStatus() as its default value and Class.getDesiredAssertionStatus() should use VMClassLoader.defaultSystemAssertionStatus() for system classes. I understand that this would be a rather big change because all VMs using GNU Classpath will fail if they do not adopt their VMClassLoader accordingly. I want to revitalize the discussion on this topic and I'm ready to prepare a patch for this issue but things should be discussed first ;). I hope my explanations are somehow understandable ;). - josef PS: I think the patch from 2007 is does not fix this issue as it does not modify java.lang.Class and java.lang.Classloader receptively.

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 JamVM, CACAO and Kaffe can make use of an installed copy of GNU Classpath 0.99, while GCC (gcj) will use the developer snapshots as a base for future versions. For more projects based on GNU Classpath, http://www.gnu.org/software/classpath/stories.html This release brings with it a number of interesting new features: * Addition of java.util.regex.Pattern.quote. * Addition of java.io.IOError. * Addition of java.io.Console. There have also been many bugfixes over the past year. Those relevant to 0.99 can be found at http://gcc.gnu.org/bugzilla/buglist.cgi?product=classpath&amp;target_milestone=0.99 With the 0.95 release, we switched fully towards the 1.5 generics work that we previously released separately as classpath-generics. All this work is now fully integrated in the main release and various runtimes (gcj, cacao, jamvm, ikvm, etc) have been extended to take advantage of the new generics, annotations and enumeration support in the core library. As a consequence, only 1.5 capable compilers (currently the Eclipse Compiler for Java (ecj) and Sun's javac) may be used to build Classpath. 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 gjdoc tool, which is part of GNU Classpath 0.99. Full documentation on the currently implementated packages and classes can be found at: http://developer.classpath.org/doc/ We are looking into how to extend the documentation experience in the future. Please contact the mailinglist if you would like to help with this effort.

AFAICT, we've all agreed that we'll dump CVS but left the decision open to which tool we'll migrate. What I'd personally like to see is that once 0.99 is out, we shut down CVS, convert the git mirrors to read-write git repositories: http://icedtea.classpath.org/mirror/git and keep the existing Mercurial mirroring scripts in place. Thoughts? Pekka </pre> Pekka Enberg 2012-03-12T08:53:44 http://comments.gmane.org/gmane.comp.java.classpath.devel/10320 <pre>Hello all, I would like to report an issue in the dispatchEvent() method in base class java.awt.Component. The JDK API documentation for dispatchEvent() says: "Dispatches an event to this component or one of its sub components. Calls processEvent before returning for 1.1-style events which have been enabled for the Component." According to this description, I would expect the attached sample code (see below) to output this: Dispatching action event processEvent called And in fact this is what I get when using the JDK (testing with OpenJDK 1.6.0_20). However with GNU Classpath I get this: Dispatching action event The processEvent() method is never called. I looked into the sources and found out that this happens because the eventTypeEnabled() method in Classpath's implementation of Component does not know about action events and will always return "false" even if action events have been enabled. While not an issue when using AWT heavyweight components, this may break lightweight components that generate action events (which is how I found this in the first place). === Sample code === import java.awt.*; import java.awt.event.ActionEvent; public class Sample extends Component { protected void processEvent(AWTEvent e) { System.out.println("processEvent called"); super.processEvent(e); } public void simulateActionEvent() { System.out.println("Dispatching action event"); enableEvents(AWTEvent.ACTION_EVENT_MASK); ActionEvent ev = new ActionEvent(this, ActionEvent.ACTION_PERFORMED, "test"); dispatchEvent(ev); } public static void main(String args[]) { Sample sample = new Sample(); sample.simulateActionEvent(); } } === Sample code === Best regards, Guillermo Rodriguez Garcia guille.rodriguez&lt; at &gt;gmail.com </pre> Guillermo Rodriguez Garcia 2012-01-23T16:15:41 http://comments.gmane.org/gmane.comp.java.classpath.devel/10319 <pre> Hi All, I want to include JSR 177, JSR 120, JSR 205, with GNU classpath.

Happy hacking, Brian </pre> Brian Jones 2012-01-05T02:11:15 http://comments.gmane.org/gmane.comp.java.classpath.devel/10311 <pre>The latest release Jato 0.3 is now available. The release tarball can be found here: http://www.kernel.org/pub/software/java/jato/jato-0.3.tar.bz2 The Git repository can be found here: https://github.com/penberg/jato About Jato ========== Jato is an open source, JIT-only virtual machine for Java that aims to support the latest JVM specification. It can currently run many Java applications such as JRuby, Clojure, and Eclipse on 32-bit x86 Linux machines. Ports to x86-64, ARM, and PPC32 CPUs and Darwin OS are currently under development. Release Notes ============= Applications ------------ * JRuby and Jython are now supported. - GNU Classpath CVS HEAD is required. [ See below for details how to download and install it. ] Performance ----------- * VM startup speed has improved by 25%. * DaCapo benchmark results have improved across the board. - See the following URL for DaCapo results: http://i.imgur.com/eorgM.png JIT --- * The JIT compiler is now able to optimize code before execution. - Transformation of the IR to SSA form and out of SSA form. [ SSA form is not enabled by default. Use '-Xssa' command line option to enable it. ] - Dead code elimination optimization (requires SSA). - Array bounds check elimination (requires SSA). - Inline caching optimization is used on i386 architecture. * The JIT compiler has limited support for ARM and PPC32 architectures. - Don't expect to run real applications on them, though. * The JIT compiler support on the x86-64 architecture has improved significantly. - Not as mature as i386 architecture. VM -- * The VM has a classfile verifier. - It is able to detect classfile corruption and many semantic problems in bytecode. * The VM supports most of the JNI API. GNU Classpath ============= Please use GNU Classpath CVS HEAD with Jato 0.3 for best performance and compatibility.

This process should happen in the next few days. Anyway, the name servers for the domain are not supposed to change during this transfer process so this should be transparent to everyone involved, but in case something happens I wanted to at least let folks know it was going on. Happy hacking, Brian </pre> Brian Jones 2012-01-05T02:11:15 http://comments.gmane.org/gmane.comp.java.classpath.devel/10311 <pre>The latest release Jato 0.3 is now available. The release tarball can be found here: http://www.kernel.org/pub/software/java/jato/jato-0.3.tar.bz2 The Git repository can be found here: https://github.com/penberg/jato About Jato ========== Jato is an open source, JIT-only virtual machine for Java that aims to support the latest JVM specification. It can currently run many Java applications such as JRuby, Clojure, and Eclipse on 32-bit x86 Linux machines. Ports to x86-64, ARM, and PPC32 CPUs and Darwin OS are currently under development. Release Notes ============= Applications ------------ * JRuby and Jython are now supported. - GNU Classpath CVS HEAD is required. [ See below for details how to download and install it. ] Performance ----------- * VM startup speed has improved by 25%. * DaCapo benchmark results have improved across the board. - See the following URL for DaCapo results: http://i.imgur.com/eorgM.png JIT --- * The JIT compiler is now able to optimize code before execution. - Transformation of the IR to SSA form and out of SSA form. [ SSA form is not enabled by default. Use '-Xssa' command line option to enable it. ] - Dead code elimination optimization (requires SSA). - Array bounds check elimination (requires SSA). - Inline caching optimization is used on i386 architecture. * The JIT compiler has limited support for ARM and PPC32 architectures. - Don't expect to run real applications on them, though. * The JIT compiler support on the x86-64 architecture has improved significantly. - Not as mature as i386 architecture. VM -- * The VM has a classfile verifier. - It is able to detect classfile corruption and many semantic problems in bytecode. * The VM supports most of the JNI API. GNU Classpath ============= Please use GNU Classpath CVS HEAD with Jato 0.3 for best performance and compatibility. You can use the following Git mirror to fetch the sources: git://icedtea.classpath.org/mirror/git/classpath/classpath See the README file in Jato's source tree for details on how to install GNU Classpath on your machine.

This process should happen in the next few days. Anyway, the name servers for the domain are not supposed to change during this transfer process so this should be transparent to everyone involved, but in case something happens I wanted to at least let folks know it was going on. Happy hacking, Brian </pre> Brian Jones 2012-01-05T02:11:15 http://comments.gmane.org/gmane.comp.java.classpath.devel/10311 <pre>The latest release Jato 0.3 is now available. The release tarball can be found here: http://www.kernel.org/pub/software/java/jato/jato-0.3.tar.bz2 The Git repository can be found here: https://github.com/penberg/jato About Jato ========== Jato is an open source, JIT-only virtual machine for Java that aims to support the latest JVM specification. It can currently run many Java applications such as JRuby, Clojure, and Eclipse on 32-bit x86 Linux machines. Ports to x86-64, ARM, and PPC32 CPUs and Darwin OS are currently under development. Release Notes ============= Applications ------------ * JRuby and Jython are now supported. - GNU Classpath CVS HEAD is required. [ See below for details how to download and install it. ] Performance ----------- * VM startup speed has improved by 25%. * DaCapo benchmark results have improved across the board. - See the following URL for DaCapo results: http://i.imgur.com/eorgM.png JIT --- * The JIT compiler is now able to optimize code before execution. - Transformation of the IR to SSA form and out of SSA form. [ SSA form is not enabled by default. Use '-Xssa' command line option to enable it. ] - Dead code elimination optimization (requires SSA). - Array bounds check elimination (requires SSA). - Inline caching optimization is used on i386 architecture. * The JIT compiler has limited support for ARM and PPC32 architectures. - Don't expect to run real applications on them, though. * The JIT compiler support on the x86-64 architecture has improved significantly. - Not as mature as i386 architecture. VM -- * The VM has a classfile verifier. - It is able to detect classfile corruption and many semantic problems in bytecode. * The VM supports most of the JNI API. GNU Classpath ============= Please use GNU Classpath CVS HEAD with Jato 0.3 for best performance and compatibility. You can use the following Git mirror to fetch the sources: git://icedtea.classpath.org/mirror/git/classpath/classpath See the README file in Jato's source tree for details on how to install GNU Classpath on your machine. Support ======= If you have questions, comments, or suggestions, feel free to drop by at #jato on irc.freenode.net or send an email to our mailing list at: http://groups.google.com/group/jatovm?hl=en You can also report problems on Github: https://github.com/penberg/jato/issues For more information, please check out the Jato home page: http://www.jatovm.org/ --- Changes from v0.2 to v0.3 ========================= The following changes since commit 08c53b4aab143072eb77c505ad90a3dcdf501b9c: Jato 0.2 (2011-05-24 23:06:27 +0300) are available in the git repository at: git&lt;

First they will move today/tomorrow to a slower connection, and then one or two weeks later they will hopefully move to a much faster connection. Each time the IP addresses will change. This might cause some unexpected downtime or make the servers unreachable for some time. You might notice some warnings emitted when committing to one of the repositories that trigger the buildbot when it cannot reach builder.classpath.org. These are "harmless", except that your commit will not be tested by the autobuilders. So please be extra careful what you commit in the next couple of days. Apologies for the inconvenience, Mark </pre> Mark Wielaard 2011-12-08T11:24:01 http://comments.gmane.org/gmane.comp.java.classpath.devel/10303 <pre></pre> Andrew Haley 2011-11-28T16:17:00 http://comments.gmane.org/gmane.comp.java.classpath.devel/10301 <pre>Hi, Thanks to Pekka Enberg there are now experimental hg and git mirrors of all the GNU Classpath and Mauve CVS repository modules on icedtea: http://icedtea.classpath.org/mirror/hg/ http://icedtea.classpath.org/mirror/git/ They should sync each hour and update. Note that they are read-only, experimental and we reserve the right to regenerate them. In fact, if you find anything odd or just plain wrong with them, please let us know. And we will try to regenerate them more correctly. Although CVS just doesn't have all the necessary information to make them perfect, so some issues will sadly only be "correct by approximation". Cheers, Mark P.S. For people wanting to try this at home. Both savannah and sourceware let you rsync the complete raw CVS repository: rsync://sourceware.org/mauve-cvs/ rsync://cvs.savannah.gnu.org/sources/classpath/ You need to have: - git cvsimport (git-cvs) - hg convert (add [extensions] hgext.convert= to ~/.hgrc) The attached ./mirror-cvs uses those and the config files to create the git and hg repos from the CVS repositories. </pre> Mark Wielaard 2011-10-10T09:04:15 http://comments.gmane.org/gmane.comp.java.classpath.devel/10294 <pre>Hi all, I'm seeing this on Fedora 15: [penberg&lt; at &gt;tux classpath.cvs]$ sh autogen.sh configure.ac:505: warning: AC_LIB_PREPARE_PREFIX is m4_require'd but not m4_defun'd m4/iconv.m4:11: AM_ICONV_LINKFLAGS_BODY is expanded from... m4/iconv.m4:22: AM_ICONV_LINK is expanded from... m4/iconv.m4:77: AM_ICONV is expanded from... configure.ac:505: the top level configure.ac:505: warning: AC_LIB_RPATH is m4_require'd but not m4_defun'd m4/iconv.m4:11: AM_ICONV_LINKFLAGS_BODY is expanded from... m4/iconv.m4:22: AM_ICONV_LINK is expanded from... m4/iconv.m4:77: AM_ICONV is expanded from... configure.ac:505: the top level configure.ac:505: warning: AC_LIB_PREPARE_PREFIX is m4_require'd but not m4_defun'd m4/iconv.m4:11: AM_ICONV_LINKFLAGS_BODY is expanded from... m4/iconv.m4:22: AM_ICONV_LINK is expanded from... m4/iconv.m4:77: AM_ICONV is expanded from... configure.ac:505: the top level configure.ac:505: warning: AC_LIB_RPATH is m4_require'd but not m4_defun'd m4/iconv.m4:11: AM_ICONV_LINKFLAGS_BODY is expanded from... m4/iconv.m4:22: AM_ICONV_LINK is expanded from... m4/iconv.m4:77: AM_ICONV is expanded from... configure.ac:505: the top level libtoolize: putting auxiliary files in `.'. libtoolize: copying file `./ltmain.sh' libtoolize: putting macros in AC_CONFIG_MACRO_DIR, `m4'. libtoolize: copying file `m4/libtool.m4' libtoolize: copying file `m4/ltoptions.m4' libtoolize: copying file `m4/ltsugar.m4' libtoolize: copying file `m4/ltversion.m4' libtoolize: copying file `m4/lt~obsolete.m4' configure.ac:505: warning: AC_LIB_PREPARE_PREFIX is m4_require'd but not m4_defun'd m4/iconv.m4:11: AM_ICONV_LINKFLAGS_BODY is expanded from... m4/iconv.m4:22: AM_ICONV_LINK is expanded from... m4/iconv.m4:77: AM_ICONV is expanded from... configure.ac:505: the top level configure.ac:505: warning: AC_LIB_RPATH is m4_require'd but not m4_defun'd m4/iconv.m4:11: AM_ICONV_LINKFLAGS_BODY is expanded from... m4/iconv.m4:22: AM_ICONV_LINK is expanded from... m4/iconv.m4:77: AM_ICONV is expanded from... configure.ac:505: the top level configure.ac:505: warning: AC_LIB_PREPARE_PREFIX is m4_require'd but not m4_defun'd m4/iconv.m4:11: AM_ICONV_LINKFLAGS_BODY is expanded from... m4/iconv.m4:22: AM_ICONV_LINK is expanded from... m4/iconv.m4:77: AM_ICONV is expanded from... configure.ac:505: the top level configure.ac:505: warning: AC_LIB_RPATH is m4_require'd but not m4_defun'd m4/iconv.m4:11: AM_ICONV_LINKFLAGS_BODY is expanded from... m4/iconv.m4:22: AM_ICONV_LINK is expanded from... m4/iconv.m4:77: AM_ICONV is expanded from... configure.ac:505: the top level configure:18566: error: possibly undefined macro: AC_LIB_PREPARE_PREFIX If this token and others are legitimate, please use m4_pattern_allow.

Pekka </pre> Pekka Enberg 2011-09-27T12:31:43 http://comments.gmane.org/gmane.comp.java.classpath.devel/10289 <pre>Hi all, I started hacking on invokedynamic again: https://github.com/penberg/classpath/commit/21c457f4928678bb5709dfc5a992b80f0d02c4b8 https://github.com/penberg/jato/commits/indy I'm planning to use ASM for generating bytecode for method handle chains. Does that sound like a reasonable thing to do? We already carry the ASM code under tools/external/asm/. Can I just move that under external/ and rename the package so that it doesn't clash with the upstream project?
