aot-compile-rpm problem
by Anthony Green 23 Aug '06

23 Aug '06

Hi, On rawhide, when I do a "yum install java-1.4.2-gcj-compat-devel" on my x86-64 system I get both the x86-64 and x86 packages. I suppose the x86 version is written last, because aot-compile-rpm's LIBDIR is set to /usr/lib/gcj instead of /usr/lib64/gcj. This pretty much breaks rpm building. The fix is to make sure I just "yum install java-1.4.2-gcj-compat-devel.x86_64". Is this expected behaviour? I don't remember this being a problem for my in the past. Thanks, AG

This should probably go in the java-1.4.2-gcj-compat package (our JDK compatibility layer on top of gcj). We could simply "BuildRequire" openssl to generate and package the cacerts files. > Does that make sense?

gcjwebplugin has landed in Rawhide
by Thomas Fitzsimmons 03 Aug '06

03 Aug '06

Hi, gcc-4.1.1-12, which contains libgcjwebplugin.so, went into Rawhide last night along with java-1.4.2-gcj-compat-plugin which installs an alternatives-managed "libjavaplugin.so" symlink in /usr/lib/mozilla/plugins. I closed the long-standing "Inclusion of gcjwebplugin" bug: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=127537 and updated the release notes with a "Handling Java Applets" section: http://fedoraproject.org/wiki/Docs/Beats/Java Rawhide users can install gcjwebplugin with "yum install java-1.4.2-gcj-compat-plugin". Please try this out, file bugs and comment on the release note additions. The GNU Classpath AWT and Swing code was in a state of flux when the backport that included gcjwebplugin was done (because of a large Java2D rewrite to make the Cairo backend the default), so there are some regressions in AWT and Swing applications for FC6test2. My post-test2 plan for gcjwebplugin is to gage the reaction of Rawhide users, and also to do another GUI backport from GNU Classpath HEAD to Fedora's libgcj, to fix the AWT and Swing regressions. If the reaction turns out to be overly negative, even after the new AWT and Swing backport, we can always make gcjwebplugin not installed by default, for FC6test3. For FC6test2 though, it is installed by default if the Internet group is selected. Tom

fc6 extras java status
by Anthony Green 01 Aug '06

01 Aug '06

Things are a little ugly in fc6 extras java land... * Azureus makes my computer practically unusable because of libgcj's new SecureRandom implementation. I've filed a bug for a work around here: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=200653 Mark tells me this is the root cause of some crypto test timeout problems on the autobuilder as well. Casey says that this same code doesn't seem to have a problem on jamvm. * RSSOwl no longer fails to start because of the zip problem (thanks tromey!), but now crashes in _Jv_ClassReader::checkExtends (super = 0x3). I'm rebuilding libgcj with -O0 -g3 to debug. * I've updated jogl to jsr231 1.0 beta 5. The good news is that it builds sans patching! The bad news is that demos crash the X server (like, try resizing the gears demo). I think this is an X problem, so I'm going to push this out anyways because the latest WW2D (and "WW2D plus one", which looks awesome -- http://www.alpix.com/3d/worldwin/WW2d_Java.html) use this version of the jogl API. * kawa is fine.

Do we still need these packages in fc6 or did they get merged into libgcj? Anybody know? Thanks, AG

ssl connections, cacerts

Now that rssowl is running (thanks aph), I wanted to see if https rss feeds would work (like those provided by bugzilla). Our classpath.security file is messed up, but I think fitzsim just fixed this: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=200701 When I fix it manually, and try to access an https rss feed, I get... Exception in thread "Load Feed Thread" org.apache.commons.httpclient.HttpClientError: java.security.KeyStoreException: java.io.FileNotFoundException: /usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre/lib/security/cacerts (No such file or directory) at net.sourceforge.rssowl.dao.ssl.EasySSLProtocolSocketFactory.createEasySSLContext(Unknown Source) at net.sourceforge.rssowl.dao.ssl.EasySSLProtocolSocketFactory.getSSLContext(Unknown Source) at net.sourceforge.rssowl.dao.ssl.EasySSLProtocolSocketFactory.createSocket(Unknown Source) at org.apache.commons.httpclient.HttpConnection.open(jakarta-commons-httpclient-3.0.jar.so) at org.apache.commons.httpclient.HttpMethodDirector.executeWithRetry(jakarta-commons-httpclient-3.0.jar.so) at org.apache.commons.httpclient.HttpMethodDirector.executeMethod(jakarta-commons-httpclient-3.0.jar.so) at org.apache.commons.httpclient.HttpClient.executeMethod(jakarta-commons-httpclient-3.0.jar.so) at org.apache.commons.httpclient.HttpClient.executeMethod(jakarta-commons-httpclient-3.0.jar.so) at net.sourceforge.rssowl.dao.ConnectionManager.openConnection(Unknown Source) at net.sourceforge.rssowl.dao.ConnectionManager.connect(Unknown Source) at net.sourceforge.rssowl.dao.ConnectionManager.connect(Unknown Source) at net.sourceforge.rssowl.dao.NewsfeedFactory.initXmlDocument(Unknown Source) at net.sourceforge.rssowl.dao.NewsfeedFactory.<init>(Unknown Source) at net.sourceforge.rssowl.dao.NewsfeedFactory.<init>(Unknown Source) at net.sourceforge.rssowl.controller.thread.FeedLoader.run(Unknown Source) We don't have a cacerts file.

Regression in libgcj: spurious IncompatibleClassChangeError with BC-compiled code.
by Andrew Haley 25 Jul '06

25 Jul '06

This happens if a class and its superclass are loaded by the boot classloader. If one if them is in the precompiled database and one isn't, we fail this check: if ( sub->loader != super->loader || !_Jv_ClassNameSamePackage (sub->name, super->name)) { throw_incompatible_class_change_error (sub->getName ()); } We fail this check becasue of this line in natVMClassLoader.cc // Record the defining loader. For the bootstrap class loader, // we record NULL. if (loader != bootLoader) klass->loader = loader; So, at the point of this test: sub->loader != super->loader sub->loader == bootLoader, and super->loader == NULL. All this happens because when a class is loaded by natSharedLibLoader, we do this: void _Jv_sharedlib_register_hook (jclass cls) { cls->protectionDomain = curHelper->domain; cls->loader = curLoader; if (! cls->engine) cls->engine = &_Jv_soleCompiledEngine; curHelper->registerClass(cls->getName(), cls); } note that we always set the loader; we don't check for it being the bootLoader. There are several ways to fix this. We need it for FC6.
