Subject [jira] [Created] (SOLR-9229) TestNRTOpen.testSharedCores() failures
Date Mon, 20 Jun 2016 16:13:05 GMT
Steve Rowe created SOLR-9229:
--------------------------------

             Summary: TestNRTOpen.testSharedCores() failures
                 Key: SOLR-9229
                 URL: https://issues.apache.org/jira/browse/SOLR-9229
             Project: Solr
          Issue Type: Bug
            Reporter: Steve Rowe


My Jenkins found a reproducing TestNRTOpen.testSharedCores() failure on branch_5_5, and git
bisect pointed the finger at SOLR-9034:

But Policeman Jenkins found another reproducing branch_5_5 seed [http://jenkins.thetaphi.de/job/Lucene-Solr-5.5-Linux/310/consoleText],
and {{git bisect}} instead blames SOLR-8621:

And when I go back and look at Jenkins emails, the first modern failure for this test was
just a couple hours after SOLR-8621 was committed [http://jenkins.thetaphi.de/job/Lucene-Solr-5.x-Linux/15516/]
- this reproduces for me on current branch_5_5:

{noformat}

-Dtests.seed=1A4EC986938AC08C -Dtests.multiplier=3 -Dtests.slow=true -Dtests.locale=en-PH

  [junit4] FAILURE 0.31s J1 | TestNRTOpen.testSharedCores <<<

  [junit4]    > 	at org.apache.solr.core.TestNRTOpen.testSharedCores(TestNRTOpen.java:116)
{noformat}

However, when the above seed fails on my box, the point at which the failure occurs as well
as the cause are different from above:
