Patrick Linskey commented on OPENJPA-367:
-----------------------------------------
That sounds like a valid fix to me.
> PCEnhancer does not find meta data for entities using pure XML annotation

> Key: OPENJPA-367
> URL: https://issues.apache.org/jira/browse/OPENJPA-367
> Project: OpenJPA
> Issue Type: Bug
> Components: kernel
> Affects Versions: 1.0.0
> Environment: All platforms
> Reporter: Albert Lee
> Assignee: Albert Lee
> Attachments: OPENJPA-367.patch, OPENJPA-367.test.jar

>
> When an entity is defined using pure XML (i.e. no annotation in the entity
> class), the enhancer does not recognized the meta data and no enhancing will
> take place: E.g.
