Bug#1006532: libjogl2-java: Profile GL4bc is not available on X11GraphicsDevice

[Owen Riddy]

To help narrow down the problem I compiled JOGL from the source master branch 
(https://jogamp.org/jogl/doc/HowToBuild.html JOGL HEAD commit ecf6e499d, glugen 
HEAD commit 0b441cfc) & the Clojure code executed without the exception. I 
could get my old code to display as well. This bug may have been fixed as part 
of JOGL 2.4.0 development.
