--------------------------------------------

             Summary: Scheduler: misconfigured job should not disable all other jobs on activate()
                 Key: SLING-4898
                 URL: https://issues.apache.org/jira/browse/SLING-4898
             Project: Sling
          Issue Type: Bug
          Components: Commons
    Affects Versions: Commons Scheduler 2.4.8
            Reporter: Alexander Klimetschek


Upon start of the scheduler bundle, if one Job is misconfigured and an exception is thrown like below, all other Jobs tracked by the ServiceTracker will be ignored since the exception bubbles up.

I guess it should be isolated by catching any exception when [calling register()|https://github.com/apache/sling/blob/dbf5122bb38cd011a5cd88cd6540acf8a98a9e82/bundles/commons/scheduler/src/main/java/org/apache/sling/commons/scheduler/impl/WhiteboardHandler.java#L75].
