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 t
ransactions. The changes in the cache must not be visible in the datastore or timeou
ts will occur. The exception here occurs when the second optimistic JDO transaction
att
empts to read a row that has been changed in the cache by the first optimistic JDO transacti
on.
