Error description
When a JPQL query is run to retrieve a field of a JPA Entity, JPA should return the correct Java type as defined in the JPA Entity. However, when a field defined as an @Version, and a type of Long or Short, the returned field type is an Integer.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V8.0.0, V8.5.0, and V8.5.5 who make * * use of a JPA @Version field. * **************************************************************** * PROBLEM DESCRIPTION: Version field in a JPA projection * * always returned as an Integer. * **************************************************************** * RECOMMENDATION: * **************************************************************** There is 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 results are the same for the other supported types, except for Timestamp.
Problem conclusion
With this fix, code has been added to OpenJPA to ensure that an @Version field returned from a query is of the correct type. The fix for this APAR is currently targeted for inclusion in Service Levels (Fix Packs) 8.0.0.9 and 8.5.5.2 of WebSphere Application Server versions 8.0.0 and 8.5.5.
