Sounds like a typical multithreading race...
Was XInitThreads() called before?

Some older platforms?
E.g. all our enterprise products... None of them have xcb yet.

And as java is used for applets, there is a big chance that this code
will run on older systems.

You need X11 for GLX (which is the protocol level of OpenGL). There is
AFAIK no GLX binding to xcb yet.
