The Equipment and EquipmentHolder is defined as OneToOne relationship. The Equipment entity has a record in table and EquipmentHolder does not have any matching records. The EclipseLink is returning the vector with size 1 and has no elements in it when used the "select o.equipmentHolders from Equipment o where o.entityId = 9000001" JPQL query.
Recently upgraded from Weblogic 11g to 12.1.3. This used to work earlier. This is an regression compared with earlier EclipseLink. Could some tell how to go with this issue.
The details are given below:
Environment:
Weblogic : 12.1.3
EclipseLink : 2.5.2.v20140319-9ad6abd
When using the following JPQL the getResultList on Query is returning the vector with size 1 and has no elements it it.
javax.persistence.EntityManager em = PersistenceHelper.makePersistenceManager().getPersistenceManager();
javax.persistence.Query query = em.createQuery("select o.equipmentHolders from Equipment o where o.entityId = 9000001");
Collection result = query.getResultList();
The following is the logs generated for the above query:
