Hi Wan-Teh, Before I try to get the stack track using gdb on the core file, as I made it to crash with your suggested change, Java crashed with this error. Actually it also stack trace. Can you see anything from it.
I appreciate your help. This is a must fix for us. # # An unexpected error has been detected by Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x712a97e2, pid=10873, tid=1904720784 # # Java VM: Java HotSpot(TM) Client VM (1.6.0_01-b06 mixed mode) #
