Description

SOLR-4909 added TestNonNRTOpen on Sep 10, 2013 - since then the policeman jenkins server has reported TestNonNRTOpen.testReaderIsNotNRT failing 33 times by my count – but i've never been able to reproduce, nor have I seen any similar failures from apache jenkins.

The failures are all virtually identical, and seem to happen just as likely on 4x/trunk, mac/linux/windows, 1.6/1.7/1.8
