Stefan Egli commented on SLING-5267:
------------------------------------
the test actually had a bug: it was assuming 0 events to be received at a
certain point - even though there was the possibility that an event
(TOPOLOGY_INIT) was already sent then.
> TestOakSyncTokenService.testTwoNodesOneLeaving failed on jenkins, again
