Catalina Wei resolved OPENJPA-961.
----------------------------------

       Resolution: Fixed
    Fix Version/s: 2.0.0

work remains to complete full support of element collection in query;
when an identification variable is defined over an element collection, this identifier can
appear as an argument of  INDEX or TYPE functions, or could be referenced is where clause
or further navigated down the path.
These  will be address in sub-task of iteration 6.

> This task is to support projection of element collection elements within a JPQL query.
 Ex.  (SELECT b FROM ColEnt a JOIN a.coll b)  where coll is an element collection within entity
A.  There are some assertions commented out in TestOrderColumn.java that use JPQL for validation.
 They can be used to help test this task.
> // This validator is disabled until INDEX projection supports element 
> // collections
> //        validateIndexAndValues(em, "BaseTestEntity", "collelems", 10, 
> //                new Object[] { elems[0], elems[1], elems[2]} "id",
> //                bte.getId());
> and 
> //      This validator is disabled until INDEX projection supports element 
> //      collections
> //        validateIndexAndValues(em, "Owner", "bikeColl", 0, 
> //                bikeArr, "id", 
> //                oid);
