I built the javax-usb package and try to run my application on the same
machine.
The current installed JVM is java 1.4.2-b28.
When trying to run the program, the following error is returned :
###########################
An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0x42073499

Can you attach the output from the JVM crash? Also, what JVM are you
using?
Also, I'm assuming you built the linux package on that system...?
