Hi

Several JOGL NEWT applications sometimes get frozen when NEWT tries to get the XRandR version number and I get (very rarely) this exception:
Exception in thread "main" java.lang.NullPointerException
	at jogamp.newt.MonitorModeProps.streamInMonitorDevice(MonitorModeProps.java:223)
	at jogamp.newt.ScreenImpl.getVirtualMonitorDevice(ScreenImpl.java:483)
	at jogamp.newt.ScreenImpl.initMonitorState(ScreenImpl.java:527)
	at jogamp.newt.ScreenImpl.createNative(ScreenImpl.java:184)
	at jogamp.newt.ScreenImpl.addReference(ScreenImpl.java:222)
	at engine.service.Ardor3DGameServiceProvider.<init>(Ardor3DGameServiceProvider.java:217)
	at engine.service.Ardor3DGameServiceProvider.main(Ardor3DGameServiceProvider.java:119)

This isn't always reproducible but it becomes very annoying and it happens more frequently in latest builds.

Hi

I obtain this with the RC12:

I get this with JOGL 2.0.2:

It's no longer reproducible with JOGL 2.2.1.
