Actually, when those attributes are set to true, jReality uses GL_LINES and GL_POINTS, drawing these primitives can be very slow and is badly handled with shaders. On some graphics cards it is even not accelerated.

jReality uses a lot of display lists. Nowadays, they are badly implemented, the most accelerated paths use VBOs.

As the problem is related on jReality, maybe its users might help you better than us.
