Hello !
I have a thread in my application, which starts a Canvas3D and loads a
vrml-file.
When this thread is stopped, the whole java3d-stuff is disposed.
After a while, if the application is closed (the java3d is already gone
and the thread is gone, too) I get the following:
Exception during disposal:
java.lang.reflect.InvocationTargetException:
java.lang.NullPointerException

any idea, what's happening here ?
thanx for your support,
