Joerg,
Thanks for your bug report. It is a regression bug in Java 3D 1.3
beta1 and 2. Too bad we were unable to uncover this bug earlier, so it
will *not be* in the coming Java 3D 1.3 FCS release. We will try to
understand the cause of this bug. We'll post a workaround to this bug on
the alias, if we found one.
thanks,
- Chien Yang.
Java 3D Team.
