Adding the GLProfile.initSingleton() didn't help.  The problem appears to be occurring somewhere in the native code.  Looking at the thread stack traces, it looks as if the NEWT windows thread is waiting on the AWT thread to change the focus.  Enabling all JOGL debugging also shows that the system is still attempting to render, as I continue to see "SwapBuffers calls: ..." messages.
