I modified the Java3D demo program "AppearanceTest" to mimic the behavior that was failing for my application. I attached the source and bytecode if you want to check it out...
Of course, it's not like I can look forward to having it fixed anytime soon...
If I carry a picket sign outside of Macintosh until they spend the money on a Java3D liscense, would Sun then hire back Mark Hood and Kelvin Chung to help me out??!!

The spheres are initially all given their own Appearance with a Red material.
