This is a well known bug in Java3D. You must be using Java3D version
1.1.3 or 1.2. You can get version 1.1.2 for Windows and Solaris from
the VisAD web page, and 1.1.2 does not have this bug. Or you can
download Java3D version 1.2.1 beta 2 from Sun (which has a few small
problems but at least does not seem to throw Exceptions). We are
working closely with the Sun Java3D team to ensure that version 1.2.1
won't have any show-stopper bugs for VisAD.
By the way, you emailer does not insert end-of-line characters in
your emails, which make them a bit hard to read (leads me to believe
you are running on Windows). If you can fnd a way to put end of line
characters in, that would be nice.
Cheers,
Bill
