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

             Summary: Exception thrown on Sling Starter shutdown in JobManagerConfiguration
                 Key: SLING-10938
                 URL: https://issues.apache.org/jira/browse/SLING-10938
             Project: Sling
          Issue Type: Task
          Components: Event
    Affects Versions: Event 4.2.24
            Reporter: Michał Goliński
         Attachments: stacktrace.txt

On stopping the Sling Starter with Ctrl+C we can occasionally see the following stacktrace:
{code:java}
ERROR : bundle org.apache.sling.event:4.2.20 (151)[org.apache.sling.event.impl.jobs.config.JobManagerConfiguration(247)] : The activate method has thrown an exception

This doesn't nappen every time, but I've seen up to seven of these at a time (the number of stacktraces changes), see the attached file. This might be similar to SLING-10204 , although in the debugger I can see the ServiceUserMapped being mentioned, not ResourceResolverFactory.
