> Key: OPENJPA-2435
> URL: https://issues.apache.org/jira/browse/OPENJPA-2435
> Project: OpenJPA
> Issue Type: Bug
> Components: jdbc
> Affects Versions: 2.1.0, 2.3.0, 2.2.2, 2.2.1.1
> Reporter: Heath Thomann
> Assignee: Heath Thomann
> Fix For: 2.1.2, 2.3.0, 2.2.1.1, 2.2.3

>
> 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
