As far as I remember, Apple Java3D 1.3 and JOGL 1 were still under OS X 10.11, maybe you already removed them earlier.

The GPL is viral unlike the Apache 2.0 license. JNDT injects some parts of itself into the bundles which drives it unusable in non GPL programs. The choice of the license for your own code is entirely up to you. The GPL v3 is compatible with the Apache 2.0 license:
