If I start eclipse with this command line: LD_LIBRARY_PATH=plugins/org.eclipse.swt.gtk_2.1.0/os/linux/x86 ./eclipse -debug -vm /usr/local/kaffe/bin/java it's running for some time, then complains that the workspace layout could not be restored and finally quits with an OutOfMemoryError Greetings, Helmer ___ kaffe mailing list [EMAIL PROTECTED] http://kaffe.org/cgi-bin/mailman/listinfo/kaffe

That sure looks a little bit weird, but I think it's ok. And it definitely worked before we implemented the AppClassLoader stuff It finally turned out to be a bug in java.net.URLClassLoader: java.net.URLClassLoader.findClass() tries to find the .class file using findResource(). PlatformClassLoader.findResource() however delegates the call to findResource() to the xmlClassLoader which succeeds in loading that resource, which in turn causes the PlatformClassLoader to succeed in loading that class :( Fix is in CVS. Next problem is a failure in System.arraycopy() Thanks, Helmer ___ kaffe mailing list [EMAIL PROTECTED] http://kaffe.org/cgi-bin/mailman/listinfo/kaffe

O, spoke to soon... It does work. I can see BOTH the Eclipse splash
screens now! Admittedly it crashes soon after that, but this means that
it actually finishes the installation process and tries to actually
start the real application now. Joy!
Attached is the small patch that I made to the source.
And the workspace/.metadata/.log file which shows the errors while
running.
The following is my command line and the console output:
$

Nice patch. Useful info when you are playing with complex classloader hierarchies. (If you include it then I would only add the additional information if the classloaders are actaully different.) > From what I know about eclipse, I would assume that the > PlatformClassLoader should not be able to find that class, > should it? Actually it should but it does so in a tricky way and then removes (!) those classes again from the classloader. This looks like it might be the same problem that IKVM.NET had: http://weblog.ikvm.net/PermaLink.aspx/66 The workaround for IKVM.NET was to add the xmlParserAPIs.jar and xercesImpl.jar to the bootclasspath but that doesn't work for kaffe.
