             Summary: Loosen assert in IW on pending event after close
                 Key: LUCENE-5390
                 URL: https://issues.apache.org/jira/browse/LUCENE-5390
             Project: Lucene - Core
          Issue Type: Task
    Affects Versions: 4.6, 5.0, 4.7, 4.6.1
            Reporter: Simon Willnauer
            Priority: Minor
             Fix For: 5.0, 4.7, 4.6.1


Sometimes the assert in the IW is tripped due to pending merge events. Those events can always happen but they are meaningless since we close / rollback the IW anyway. I suggest we loosen the assert here to not fail if there are only pending merge events.
