Thanks for the tip :) I was looking for something like that too because I saw that ReflectionUtil.DEBUG_STATS_FORNAME field doesn't exist in JOGL 2.0.
Actually I launch the code from Eclipse using a User Library I named JOGL2.3.1.
My old user library was named JOGL2.0.
For unknown reason it seems that when I link the user library JOGL2.3.1 to a project, when launching it, the JOGL2.3.1\jogl-all.jar is used but the JOGL2.0\gluegen-rt.jar is used.I even tested to run "eclipse -clean", etc.
The solution I found is to rename the real directory of JOGL2.0 user library so that Eclipse doesn't find it.
It looks like a bug of Eclipse but I do not understand it. Another workaround may be to delete the old user library.
All work fine now!
Thank you for reading and help.

[EDIT] more precisions :)
My test Eclipse project used some other required projects that used user library JOGL2.0 leading to the behavior explained above.
