-------------------------------------
Assignee: (was: Mike Matrigali)
I am not actively working on this any more. I think it should be left open until after istat
is re-enabled or the istat tests are changed to run even if istat is disabled by default.
Then should be closed if we go a reasonable amount of time without seeing it in nightly's
or reported by anyone.

> Key: DERBY-5108
> URL: https://issues.apache.org/jira/browse/DERBY-5108
> Project: Derby
> Issue Type: Bug
> Components: Test
> Affects Versions: 10.8.0.0
> Environment: Windows platforms.
> Reporter: Kristian Waagan
> Priority: Blocker
> Attachments: javacore.20110309.125807.4048.0001.txt, waitOnShutdown.diff

>
> The test AutomaticIndexStatisticsTest.testShutdownWhileScanningThenDelete fails intermittently
on Windows platforms because the test is unable to delete a database directory.
> Even after several retries and sleeps (the formula should be (attempt -1) * 2000, resulting
in a total sleep time of 12 seconds), the conglomerate system\singleUse\copyShutdown\seg0\c481.dat
cannot be deleted.

> Maybe the database isn't shut down, or some specific timing of events causes a file to
be reopened when it shouldn't have been (i.e. after the database shutdown has been initiated).
