      Description

      I found a scenario where extra queries were being generated while cascading a persist to a new Entity. See the following example:

      @Entity
      public class CascadePersistEntity implements Serializable {
      private static final long serialVersionUID = -8290604110046006897L;

      @Id
      long id;

      @OneToOne(cascade = CascadeType.ALL)
      CascadePersistEntity other;
      ...
      }

      and the following scenario:
      CascadePersistEntity cpe1 = new CascadePersistEntity(1);
      CascadePersistEntity cpe2 = new CascadePersistEntity(2);
      cpe1.setOther(cpe2);
      em.persist(cpe1);

      This results in two inserts and one select. The extra select is what I'm going to get rid of with this JIRA.
