As you've probably guessed, the interpreter is much less well tested than the rest
of (lib)gcj. The reason your finding bugs here is possibly because nobody has tried
to do this before (that is, put a .jar file on the classpath and run something from
it ;-)

I haven't tried your test case, but I think I found the problem. Can you try the
patch below?

Any particular reason to build without threads? Was there a problem there? Just
curious...
