>> nsk.share.jdi.Debugee.waitingEvent() takes a timeout argument. However, if the call to EventQueue.remove() times out and returns null, waitingEvent() just keep on retrying. The logic is incorrect for a null result. It should immediately return null. The retry path is only meant for filtering out other events, and it updates "timeLeft' before retrying to avoid endlessly repeating the loop.
