[jira] [Commented] (SLING-5243) discovery.impl.cluster.SingleInstanceTest.testBootstrap failed on jenkins

    [ https://issues.apache.org/jira/browse/SLING-5243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14987220#comment-14987220 ] 

Stefan Egli commented on SLING-5243:
------------------------------------

the problem in this case is that during an {{analyzeVotings}} the test is reading an {{/ongoingVotings}} resource in a non-consistent (transactionally impossible) state: it looks like during creation of a new vote, the voting handler is already seeing the changes - but only partially. That results in {{voting.matchesLiveView}} to return false even though the voting hasn't been fully created yet - which is then interpreted as: ok, I have to vote no. That is wrong at that point, cos you shouldn't vote on a voting-in-creation. However, that is never possible in real-life, it must be due to the way the testing is setup.
The relevant part in the log file:
