Are you *absolutely certain* your hardware is good? We've had several reports
of JVM crashes on this list where the real problem is faulty hardware - usually
bad RAM. It's far more common than most people realise. Test by running the
application on different hardware.

The code that is closest to the crash is this OpenSymphony code, which is then
invoking something by reflection when the crash happens.
Do the crashes always happen at the same point in the code? If so, I'd ask
OpenSymphony :-). If not, I suspect bad hardware - but you might want to
analyse several crash dumps to look for common factors.
