Scott,
From the trace you aren't using j3d1.3beta1. Can you update
your Java3d to j3d1.3beta1 ? If the bug still exist, please send
us a complete test program that can reproduce your finding. From
the trace, we do know what causes the exception but we also like to
know what leads to it.
thanks,
- Chien Yang
Java 3D Team.
