test failure: 3.x IndexWriterExceptions.testRandomExceptionsThreads

steve_rowe
The Jenkins maven 3.x build failed today:

<https://builds.apache.org/job/Lucene-Solr-Maven-3.x/227/testReport/junit/org.apache.lucene.index/TestIndexWriterExceptions/testRandomExceptionsThreads/>

=====
NOTE: reproduce with: ant test -Dtestcase=TestIndexWriterExceptions -Dtestmethod=testRandomExceptionsThreads -Dtests.seed=41ed40f98cc00a8d:-5acf0be3eb47ba24:-3ad389ca2e929955
=====

This does not fail for me locally with that seed, but if I add -Dtests.iter=100, it always triggers at least one failure (three runs: 5 failures; 3 failures; 1 failure).  Maybe this is one of those tests that don't support multiple iterations, though?

Here's the output from the 100-iter run with 1 failure:
