Try sending the process a SIGQUIT or pressing Ctrl-\ at the
command line to get a thread dump. If the VM is wedged really
hard this will not produce any output, but if it does, then it's
likely a Java-level deadlock which you can diagnose with the
resulting stack traces.

Those builds were actually built on Solaris 8.

OpenGL for Java has fallback mechanisms, like using dlsym(),
built in, so this is probably benign. I don't remember precisely
whether I have seen this message on my own machine but it rings a
bell.
