I've tried to debug this issue further but have not met with success.
The only thing I could find out was that it might be a heap corruption
issue. The contents of the byte array window[] in the StreamManipulator
class from GNU Classpath seem to get overwritten. This leads to errors
when decoding the eclipse.zip file (which is contained in the jar) and
thus to to the ZipException.

I'd appreciate any tips for debugging.

I have considered trying Valgrind but I have never used it before.
Moreover, the newest release supports only up to glibc 2.16 (Ubuntu
13.04 uses glibc 2.17) so I would have to build from source. Could
Valgrind help in debugging this problem?


Kind regards,
