It's the system-wide one, from the Debian package libgl1-mesa-swx11.

>Please specify how you launch the test:

Install xvfb and libgl1-mesa-swx11, start an Xvfb server at some display, and then just run Java on that display.

>Please specify the exact Debian version you are using:
>  - cat /etc/debian_version
7.3

Also, to follow up on the above gdb attempt, I found the debug symbols lying in libgl1-mesa-swx11-dbg, and indeed, JOGL is calling glXGetFBConfigAttrib with a NULL GLXFBConfig parameter:

Breakpoint 1, glXGetFBConfigAttrib (dpy=0x8fa730, config=0x0, attribute=32784, value=0x924000) at glxapi.c:536
