Feel free to fill a bug report, please be very accurate and don't mention Java3D 1.5.2, mention the example that you use (put at least a link to its source code). In my humble opinion, you should open and close a JFrame without Java3D and you would see that there are some thread that don't die immediately even though you dispose it.
