This is not the impression given by the bug report. Perhaps
you could add your opinion at the end of:
  http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5016273

In the j3d-interest list, you're the only person to have mentioned
the bug previously.

Yes. What timer alternative did you use?

But what about uses of J3DTimer inside other
parts of Java 3D? For example, J3DTimer is used by the
SensorEventAgent class in the Java 3D utilities.
Since the timer usage is 'hidden', it may be
too difficult to substitute in another timer.

Has anyone experience of this problem?

My own guess is that System.nanoTime() and J3DTimer are implemented
on Windows in exactly the same way. So does nanoTime() fail when
J3DTimer fails?
