> The 2.2.3 has a minor regression. The ConnectionValidator#start() has been moved outside of synchronized block in this release, this leads a race condition problem.
> ConnectionValidator#start():
>  TimerUtil.schedule(this, pingPeriod); // will call ConnectionValidator.run()
>  timer = new Timer(true); // is used in ConnectionValidator.run()
> These 2 lines looks odd, because it initializes the timer for new thread after spawn the thread. In 2.2.2-SP11 the timer variable is protected by synchronized blocks, so it's not the case.
