Geoffrey, I am trying to get my head around this ticket and all the related ones. I applied your test case and after removing a couple lines from the test that I think were wrong, the test no longer fails. I added the test to both master and 5.3.x branches anyway and I am closing this ticket. Please let me know if you think there is still a problem here.

> I wrote a FailureDetectingSystemEventListener to retain the exceptions throw in the scanner, so I can fail my testcase if there are any exception is the off-threads of a testcase that should fail the test case (but currently don't).
> {code}
>         FailureDetectingSystemEventListener systemEventListener = new FailureDetectingSystemEventListener();
>         SystemEventListenerFactory.setSystemEventListener(systemEventListener);
> {code}
> However, when I tried registering this on the agent:
> {code}
>             KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("csv agent");
>             kagent.setSystemEventListener(systemEventListener);
> {code}
> It didn't work, the DoNothingSEL was still used.
> When I tried on the SystemEventListenerFactory:
> {code}
>         SystemEventListenerFactory.setSystemEventListener(systemEventListener);
> {code}
> a StackOverflowException occurs, because ProcessChangeSet.listener is a DelegatingSEL pointing to itself.
