What verson of OpenGL are you running? From what I can tell this appears to be an version specific issue.

OpengL Version: 3.1.0 - Build 9.17.10.4229

[CreedVI]

I believe the issue is that in OpenGL 3.0 glbegin() is depreciated and errors when called. Can you try manually setting your OpenGL version to 3.3 at line 953 in RLGL.java and try to run the example?
