The JOGL bindings have a problem with highly-curved geometry. The front faces don't render correctly on the screenshots of a torus shape below, seen from the front I have put a perspective view to show the actual shape. When the viewing angle is in a certain range, the rendering is broken. The same type of problem happens with other shapes, like a hemisphere, but only when you CULL_FACE is set to NONE (in order to see the concave face).
