Date Mon, 01 Feb 2016 17:30:39 GMT

     [ https://issues.apache.org/jira/browse/OAK-3937?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Julian Reschke updated OAK-3937:
--------------------------------
    Attachment: OAK-3937.diff

work in progress; with printlns added to code and test case; it seems the failure (*) has
to do with the retry logic, but so far I don't see what exactly goes wrong.

(*) as observed by the test: we don't have an "old" document for each of the ones we created/updated.
