I am sorry to say that this is a bug in Java3D, even though the
docs say it was tested (it is impossible to catch all bugs by
testing - there are just too many combinations).

And unfortunately there is no port of Java3D 1.1.2 for Linux -
the first version ported was 1.1.3 which also threw these
Exceptions.

Until Java3D version 1.2.1 is ported to Linux, there is nothing
you can do about this. Except maybe run under Windows and use
the Java3D 1.1.2 from our server.

If someone shows us an Exception from VisAD, we usually have
the fix available on our server in 24 hours. But we can't do
anything about Exceptions from Java3D but wait.

Sorry,
Bill
