Stefan Egli updated SLING-5313:
-------------------------------
Attachment: ClusterTest.testAdditionalInstance
Also attaching the full [^ClusterTest.testAdditionalInstance] that contains the
entire log of this test run. It shows that after the 'fault new voting' is
created,
instance {{c85f7fdc}} is periodically voting (whenever it receives a change
event) - but for some reason that is a) not persisted as it has to vote again
and only votes if it didn't yet and b) the other session also doesn't see the
vote, thus the vote never concludes.

> and that instance's yes vote is never seen by the other instance (session in
> the same vm). Ie although this is happening all in the same VM, one session's
> changes do not propagate to the other session. This seems to be due/related
> to the above warn.
> Looking at the used jackrabbit version it turns out sling.commons.testing
> still uses jcr-commons 2.2.9 - while we should probably use something much
> newer like 2.10
