[jira] [Created] (LUCENE-7728) TestGrouping.testRandom() failures
Steve Rowe created LUCENE-7728:
----------------------------------
Summary: TestGrouping.testRandom() failures
Key: LUCENE-7728
URL: https://issues.apache.org/jira/browse/LUCENE-7728
Project: Lucene - Core
Issue Type: Bug
Reporter: Steve Rowe
My Jenkins found a reproducing branch_6x seed:

{{git bisect}} says the first bad commit is this one: [http://git-wip-us.apache.org/repos/asf/lucene-solr/commit/6d952076], but that just removed {{BooleanSimilarity}} from the {{RandomSimilarity}}'s candidates list, which in this case likely has the side effect of picking a different similarity with this seed. So the problem is almost certainly older than this.
Policeman Jenkins reported a master seed four weeks ago [https://jenkins.thetaphi.de/job/Lucene-Solr-master-Linux/18890/] for a failure that's still reproducing for me on Linux w/ Java8:

{{git bisect}} points to the exact same first bad commit for this seed too (see above).
