new version of visad/jython giving error

I have just updated my visad/jython verion
and the program is failing with a hotspot error:
# HotSpot Virtual Machine Error, Internal Error
# Please report this error at
# Error ID: 43113F32554E54494D45110E4350500290

Any suggestions
I have put is some print statements and the error seems to move around
if I 
drop less important components of the code.
