I investigated it a bit more and got the following stacktrace:

As eclipse is up and running at this stage already and its not finding
an SWT class which exists in org.eclipse.swt.gtk.linux.x86 plugin I
think its a classloader problem with GCJ 4.0.

I tried to reproduce the same problem with SUN JDK 1.5 and it just
worked. It will be interesting to test it with kaffe when it works
again.


Cheers,
Michael
