      Description

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

      Checking out Revision c6b9ac065571718e7e92174fa7e2a927583012fa (refs/remotes/origin/branch_5_5)

      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:

      Checking out Revision c6b9ac065571718e7e92174fa7e2a927583012fa (refs/remotes/origin/branch_5_5)

      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:

        [junit4]   2> NOTE: reproduce with: ant test  -Dtestcase=TestNRTOpen -Dtests.method=testSharedCores -Dtests.seed=1A4EC986938AC08C -Dtests.multiplier=3 -Dtests.slow=true -Dtests.locale=en-PH -Dtests.timezone=America/Cayman -Dtests.asserts=true -Dtests.file.encoding=ISO-8859-1
        [junit4] FAILURE 0.31s J1 | TestNRTOpen.testSharedCores <<<

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

      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:
