TimeScheduler: if a periodic task throws an exception, task is not run again
----------------------------------------------------------------------------

                 Key: JGRP-1062
                 URL: https://jira.jboss.org/jira/browse/JGRP-1062
             Project: JGroups
          Issue Type: Bug
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 2.6.13, 2.8


When a periodic task is scheduled, e.g. with TimeScheduler.scheduleAtFixedRate()/scheduleWithFixedDelay() or scheduleWithDynamicInterval(), and the task throws an exception, then it will *not* be re-run again !

SOLUTION 1: we need to make sure that all of our tasks never throw an exception, e.g. by wrapping them into try-catch(Throwable) clauses
SOLUTION 2: with the new TimeScheduler (see [1]), we can wrap all tasks and catch all exceptions there
