> I've recreated an issue where a @Version field is returned as an Integer when the field
is defined as a Long or Short.  To explain, lets take this entity:
> @Entity
> public class LongVersionEntity implements Serializable {
> .......
>     @Version
>     protected Long version;
> .......
> With this entity take the following query:
> String str = "SELECT o.id, o.version FROM LongVersionEntity o";
> Query query = em.createQuery(str);
> List<Object[]> objectList = query.getResultList();
> for (Object[] objects : objectList) {
>     objects[1].getClass() //Will return Integer.
> Notice in this query we are selecting the version field.  When iterating over the results,
we will find that objects[1].getClass() will return Integer, rather than Long.  The same seems
to be true for the other supported types, except for Timestamp.
> I will provide a full test in the next day or so.
> Thanks,
> Heath
