I expect the threading system not to be completely innocent. If you try
to run the installer with unix-pthread (instead of unix-jthreads) it
never crashes (at least for me). However running jython seems harder, I get:
*sys-package-mgr*: processing new jar,
'/home/guilhem/ext2/PROJECTS/kaffe/libraries/javalib/kjc.jar'
*sys-package-mgr*: processing new jar, '/home/guilhem/jython-2.1/jython.jar'

Jython 2.1 on java1.3 (JIT: kaffe.jit)
kaffe-bin: machine.c:620: installMethodCode: Assertion `e->start_pc <=
e->end_pc' failed.
Do you have any idea of what is "a bad jar" ? the jitter seems also to
have some problem ...
Cheers,
Guilhem.
