_jvm- DetachCurrentThread() causes Another exception has been detected whil

Question

I have a hardware driver which calls java based on hardware interupts. The c code attaches to the current thread, calls a static method, then detaches. If I dont detatch, it works perfectly (but probably leaves the thread in limbo), but if I detach it always gives the error below. Im using jbuilder X java on windows XP, and the java callback just prints the passed parameter string. Any ideas?
Another exception has been detected while we were handling last error.
Dumping information about last error:
ERROR REPORT FILE = (N/A)
PC = 0x00a483ba
SIGNAL = -1073741819
FUNCTION NAME = (N/A)
OFFSET = 0xFFFFFFFF
LIBRARY NAME = (N/A)
Please check ERROR REPORT FILE for further information, if there is any.
Good bye.
