lwjgl issue - Java-Gaming.org

FYI, if I change the Q3FlightBenchmark class to use LWJGL instead of JOGL by the following change, I get an error.

Change:

1 2	Canvas3DWrapper canvas = Canvas3DWrapper.createStandalone(OpenGLLayer.LWJGL, //vs OpenGLLayer.JOGL Xith3DTest.DEFAULT_RESOLUTION, "Q3FlightBenchmark");

Exception:
