Subject [jira] Commented: (LUCENE-2618) Intermittent failure in 3.x's backwards TestThreadedOptimize
Date Tue, 24 Aug 2010 19:03:23 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2618?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12902018#action_12902018

Shai Erera commented on LUCENE-2618:
------------------------------------

I'm guessing that this line fails (which is 126 in my most recent checkout):

{code}
      assertTrue(reader.isOptimized());
{code}

Is this the one that's pointed by your code Mike? If so, I suggest we include a message to
the assertion, something like "index should be optimized". It's annoying that JUnit does not
print "should be true but was false", or something like that, and instead prints 'null', which
is more intimidating :).

Perhaps we should also add some more info to the print, like the number of segments in and
index and whether there are deletions, so we'd have a better clue why the test failed?

I've tried to run the test a couple of times, but it passed ...
