Is your target based on Snapgear, with uclibc?
My experience is that there is some bug in the pthreads
implementation, and I had to put the second thread in the limbo,
because it comes with the same PID or SID of the main thread, leading
to problems in the synchronization and so stopping everything or
problems on unintended sharing of thread-level-storage generating
segmentation faults or, sometimes, exceptions.

I've tried both a standard distribution of javac and the kaffe distribution
of javac and got the same results.
And I can (obviously) run a cross-compiled executable on my target.
Anything that I should take a look at? The only thing I can think of is that
it's not finding a library or that a library is out of sync. I don't have a
debugger on the target @ this time, so heading down that path is do-able,
just a lot of effort that I'm not ready for.
Thanks much,
