OpenGL 4.1 is fully supported

JOGL choses the highes available fixed function pipeline available,
ie 4.1, 4.0, 3.3, .. 2.0 .. 1.5 - or the highes programmable only one.

Hence the following unit test shall show you the highest profile, ie 4.1 if available on your platform

Using a GPU/driver w/o OpenGL 4* support, here OpenGL 3.3 only, appears as:

Have a look at those unit tests. Sure you can also try a forced a GLProfile,
however, not all are available on all machines, naturally.
