Description

The assumption in Timer appears to be that no thread will ever throw from TimerTask::fire(). In practice however few of the implementations of that method in the broker take any measures to ensure that is the case. If code called on a timer thread throws there is therefore the risk of the broker terminating (I have observed such a case for example on the management periodic processing).

It would probably be advisable to add some generic protection for this.
