      Description

      Given an entity:

      @Entity
      public class EntityB {

      @Id
      private int id;

      @ElementCollection(fetch = FetchType.EAGER)
      @CollectionTable(name = "setIntegerTable", joinColumns = @JoinColumn(name = "parent_id"))
      @Column(name = "value")
      private Set<Integer> intVals;

      ...
      }

      The following test scenario

      EntityB b1 = em.find(EntityB.class, id);
      em.clear();
      b1.getIntVals().remove(new Integer(1));
      b1.getIntVals().add(new Integer(2));

      em.getTransaction().begin();
      EntityB b2 = em.merge(b1);
      em.getTransaction().commit();
      em.clear();

      EntityB b3 = em.find(EntityB.class, id);
      Set<Integer> intVals = b3.getIntVals();
      ==> this intVals still only contains Integer(1), not Integer(2).
