The performance (and memory leak) problem is JDK1.4 bug
4470749 - Java3D fail to initialize underlying OGL/D3D library in jdk1.4
sometimes
which is fixed in the next JDK1.4 release.
The startup problem is Java3D bug which is not compatible with
JDK1.4, it will be fixed in the next java3d patch release.
