Mark Struberg commented on OPENJPA-2221:
----------------------------------------
Any special reason this fix didn't get applied to trunk as well?
> Use of AbstractValueHandler map() causes exception on find()
> ------------------------------------------------------------
>
> Key: OPENJPA-2221
> URL: https://issues.apache.org/jira/browse/OPENJPA-2221
> Project: OpenJPA
> Issue Type: Bug
> Affects Versions: 2.1.0
> Reporter: Dianne Richards
> Assignee: Jody Grassel
> Fix For: 2.1.1
>
>
> When a value strategy implemented by a subclass of AbstractValuehandler
> overrides the map() method, an exception occurs on a find() if the strategy
> is implemented on an id field. The method returns a Column[].
