Bug 524

Doing a glMaterialfv call, e.g.
glMaterialfv( GL.GL_FRONT, GLLightingFunc.GL_AMBIENT, color, 0 ), lets the JVM crash if the color parameter is null and directly passed into the native function. On my system com.jogamp.opengl.impl.gl4.GL4bcImpl.dispatch_glMaterialfv1 provokes a segfault in the graphics driver (see log).

Possible solution: let glMaterialfv do a nullpointer check
