Subject [jira] [Updated] (LUCENE-3463) Jenkins trunk tests (nightly only) fail quite often with OOM in Automaton/FST tests
Date Fri, 30 Sep 2011 22:19:46 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-3463?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Uwe Schindler updated LUCENE-3463:
----------------------------------

    Attachment: LUCENE-3463.patch

Moved the codec handling back to LTC and made the test runner more abstract. There are still
some issues with tests that create the index in BeforeClass but cannot read it later when
@UseNoMemoryExpensiveCodec is selected for one test method. Also similar issues may occur
if the test explicitely selects such a codec (Mike found some failing tests, still investigating).
