Richard Zowalla resolved OPENJPA-2513.
--------------------------------------
Resolution: Fixed
Already fixed on master: 49bbeb84f (OPENJPA-2950, ancestor of HEAD) removed the
'TODO -- need to handle subqueries': evalAccessPaths now walks the correlated
joins of the subquery (CriteriaExpressionBuilder.java:93-112), and SubqueryImpl
passes its access path to the enclosing query, which evalNavigatedAccessPaths
merges in. Closing; please reopen if this still happens with OpenJPA 4.x.

>
> Key: OPENJPA-2513
> URL: https://issues.apache.org/jira/browse/OPENJPA-2513
> Project: OpenJPA
> Issue Type: Bug
> Components: criteria, query
> Affects Versions: 2.4.0
> Reporter: Richard G. Curtis
> Assignee: Richard G. Curtis
> Priority: Major
>
> While digging into OPENJPA-2502, I discovered that
> CriteriaExpressionBuilder.evalAccessPaths(..) doesn't process subqueries when
> determining accessPaths. I don't have a very great understanding of the
> accessPath concept, but when comparing the access path of a JPQL query to a
> criteria query I can see that criteria doesn't do it the same as JPQL.
> I added a TODO in CriteriaExpressionBuilder.evalAccessPaths denoting where I
> think we have additional work.
