Hi

In my humble opinion, it has nothing to do with Java 1.8, it looks like an OpenGL problem and as Java3D is based on OpenGL, it's affected too. You probably rely on an unspecified behaviour of Nvidia graphics cards. I advise you to look at the winding of the vertices in the affected models and their respective normals. You can disable the Java2D OpenGL pipeline if you think that it might affect Java3D. There seems to be something really wrong with your normals, I have found some other anomalies. Backface culling is probably enabled in your code.
