TestIWExceptions.testRandomExceptionsThreads sometimes fails
TestIWExceptions.testRandomExceptionsThreads sometimes fails
------------------------------------------------------------
Key: LUCENE-3384
URL: https://issues.apache.org/jira/browse/LUCENE-3384
Project: Lucene - Java
Issue Type: Bug
Affects Versions: 3.4
Reporter: Robert Muir
failed in hudson (in test-backwards), with AIOOBE on termvectorswriter.
the problem with this test method is that seeds never reproduce.
But I made it fail just by doing this:
{noformat}
ant test-core -Dtestcase=TestIndexWriterExceptions -Dtestmethod=testRandomExceptionsThreads -Dtests.iter=100
{noformat}

-------------------------------------
The following seed, which triggered [a failure in today's branch_3x Jenkins Maven build|https://builds.apache.org/job/Lucene-Solr-Maven-3.x/227/testReport/junit/org.apache.lucene.index/TestIndexWriterExceptions/testRandomExceptionsThreads/] seems to trigger more failures for me locally in a 100-iter run - from one to five - than when no seed is specified (I get at most one, and sometimes zero failures, when I don't specify a seed):
{noformat}

Steven Rowe commented on LUCENE-3384:
-------------------------------------
On a different computer, the above seed improves the likelihood of failure, but is not always reproducible with a 100-iter run:
||Patch applied?||With above seed?||-Dtests.iter||\# Runs||\# Runs with at least one failure||
|No|No|100|6|0|
|No|Yes|100|6|3|
|Yes|No|100|6|0|
|Yes|Yes|100|6|3|
So the patch doesn't seem to have any effect - still 50% reproducible with the above seed.

-------------------------------------
Thanks for testing Steve... don't yet know why the patch doesnt fix it.
However, i fixed some reproducibility bugs in this test, maybe its "more reproducible" now.

-------------------------------------
After updating from svn, then applying the patch, I got 3 runs with at least one failure out of 12 100-iter runs. So it seems to be "less reproducible" now - 25% vs. 50% previously...
