Subject [jira] [Created] (OPENJPA-2435) Version field in a projection always returned as an Integer.
Date Wed, 09 Oct 2013 01:02:45 GMT
Heath Thomann created OPENJPA-2435:

             Summary: Version field in a projection always returned as an Integer.
                 Key: OPENJPA-2435
             Project: OpenJPA
          Issue Type: Bug
          Components: jdbc
    Affects Versions: 2.2.2, 2.1.0, 2.3.0,
            Reporter: Heath Thomann
            Assignee: Heath Thomann

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:

public class LongVersionEntity implements Serializable {
    protected Long version;

With this entity take the following query:

String str = "SELECT, 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.
