[jboss-jira] [JBoss JIRA] Resolved: (JGRP-1062) TimeScheduler: if a periodic task throws an exception, task is not run again

Bela Ban resolved JGRP-1062.
----------------------------

    Resolution: Done


Fixed by wrapping periodic tasks in RobustRunnable, catches runtime exceptions and logs them as errors. This can be removed when TimeScheduler has been rewritten

> 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
