Kathey Marsden reopened DERBY-4676:
-----------------------------------
reopen for 10.5 back port
> NullPointerException on SELECT on INNER JOIN
> --------------------------------------------
>
> Key: DERBY-4676
> URL: https://issues.apache.org/jira/browse/DERBY-4676
> Project: Derby
> Issue Type: Bug
> Affects Versions: 10.5.3.0, 10.6.1.0
> Environment: Windows XP, same problem occurred using Apache Derby
> 10.5.3.0 and still with the newly release 10.6.1.0 version.
> For completeness, also noting using c3p0 0.9.1-pre10 and hibernate 3.0.5.
> Attempted trying later versions of both (c3p0 and hibernate) to see if this
> resulted in a workaround, but had no success.
> Reporter: Seth Katzman
> Assignee: Knut Anders Hatlen
> Fix For: 10.6.1.1, 10.7.0.0
>

> Running into a NullPointerException error in the Apache Derby database over
> multiple versions of the derby jars. From testing, this issue intermittently
> occurs during moderate load test scenarios, but has never occurred in
> production. This is using Derby as embedded and always occurs on the same
> statement as shown below and in the attachment. Following the error,
> hibernate throws an exception which results in the code attempting to
> rollback the transaction. The rollback fails as the NullPointerException
> appears to kill the connection.
