Well as you can see,  gljCheckGL is called by GLCanvas.

gljCheckGL checks the GL error state, with the call of glGetError !
if an error occurs, it is printed plus an exception stack trace.
the error state is cleared after the call ..

to find the error, you can simply call gljCheckGL 
at many places within you display method,
but not between glBegin and glEnd !
