We have to investigate to find another way. Java3D is a bit too much permissive but only bad things can happen when you add a node and its children to the same node in a scene tree in any scenegraph API.

I advise you to look at the Java3D game "Arabian Flights" available on Sourceforge, it handles the collisions correctly.
