There were some problems with collision in the 1.1 Java 3D release,
particularly when a Group node was used as the source object in a
collision (i.e., primitives in com.sun.j3d.utils.geometry). A race
condition on the bounds access was fixed in the 1.1.1 Java 3D release,
which will be available shortly. If you continue to experience problems
with the 1.1.1 release, it would be helpful if you could send a source
code example demonstrating the problem to:
