HashedWheelTimer.stop() fails

["이희승 (Trustin Lee)"]

Hi!

That's weird.  If you called stop(), an AtomicBoolean flag is set to
true and somehow the timer thread will notice it and kill itself.  You
could confirm this behavior at: http://is.gd/d1lG1

Perhaps you could write a standalone application that reproduces the
problem so that I can reproduce the problem?

Thanks,
Trustin
