Andy Jefferson resolved JDO-72:
-------------------------------
Resolution: Fixed
Assign To: Andy Jefferson (was: Erik Bengtson)
Fixed in JPOX CVS - builds dated 29/12/2005 or later.
Now returns 3 nested exceptions, and the test passes :-)
> Test api.persistencemanager.OptimisticFailure hangs
> ---------------------------------------------------

> Key: JDO-72
> URL: http://issues.apache.org/jira/browse/JDO-72
> Project: JDO
> Type: Bug
> Components: tck20
> Environment: JPOX, Derby
> Reporter: Craig Russell
> Assignee: Andy Jefferson
>
> This test is designed to create conflicts in the database from two different
> JDO transactions. The changes in the cache must not be visible in the
> datastore or timeouts will occur. The exception here occurs when the second
> optimistic JDO transaction attempts to read a row that has been changed in
> the cache by the first optimistic JDO transaction.
