An error like that usually means that you're using mismatched versions of gcj
and libgcj. But, as you say, you're using recent snapshots of both, so I'm not
sure what the problem could be. The hanging error is most likely a generic
problem with your gcc snapshot. Have you tried using gcc 2.95.2 + java patches?
