it has happened to me with my home FreeBSD box, crashing every morning at 03:00,
after a system upgrade (i think it was from 6.2->7.1).
The easy answer was to accuse the software (upgrade), however what was most probably happening
was that the system upgrade made a previously hidden hardware problem to appear.
The system did not came back to stability, untill i replaced the motherboard.
(after having tried changing the usual suspect RAM)

The program causing the panic was periodic daily.
For some reason, the same script on the same hardware with the previous 6.2 kernel was working ok.

Anyway
Have your tried 
- native jdk 
- the binary diablo 
- the linux jdk with linuxolator
