segmentation fault

[Coleen Phillimore]

This email is for primarily for discussion about the Hotspot code base 
and not really for support.  If you think this is a bug in hotspot you 
can file a bug (as directed in the output of the crash).

 From the stack it looks like there's some bug in the native code.  Try 
running -Xcheck:jni and see if that helps diagnose your problem.
