I'm not going to let this one past.  gcj does not have "threading issues",
whatever that means, and I don't agree that it's hard to debug.  The latter
is a matter of opinion, but the former a matter of fact.

Or use a full path in dlopen().  What libraries does JCC need to open?
Just libjvm, or others?
