For non-gui apps you need to stop termination of program by
reqeusting some input. Put a System.in.read() before the
end of the main method. Thats the normal usage - see the
jmp user guide.

Yes, its known that kaffe has problem with jmp _only_ during
shutdown.

I will leave it here as I already reassigned/forwared one to kaffe and
people looking for bugs on jmp before reporting. So it might be better
to let it stay here.
