CascadeType.ALL on ManyToOne causes StackOverflow

Original report here:

Pretty easy to repro:
  @Entity
  public static class UserImpl {
    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Key key;

    @OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL, 
mappedBy = "user")
    private List<TagsRIEImpl> tagRIEs = new LinkedList<TagsRIEImpl>();

    public UserImpl() {
      this.tagRIEs.add(new TagsRIEImpl());
    }

    public Key getKey() {
      return key;
    }
  }

  @Entity
  public static class TagsRIEImpl {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Key key;

    @ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    private UserImpl user;
  }

  public void testDelete() throws Exception {
    UserImpl user = new UserImpl();
    beginTxn();
    em.persist(user);
    commitTxn();
    em.close();
    em = emf.createEntityManager();
    beginTxn();
    user = em.find(UserImpl.class, user.getKey());
    em.remove(user);
    commitTxn();
    em.close();
  }

Confirmed the same problem with DataNucleus 1.1.5 RDBMS (hsql).  I'll see if I 
can repro 
with datanuc trunk.

Confirmed the same issue with datanuc trunk.  I'll file a bug over there.

DataNucleus issue filed:
http://www.jpox.org/servlet/jira/browse/NUCCORE-435

Even if it gets fixed immediately it won't be accessible in GAE until we 
upgrade to 
DataNuc 2.0 which is still a little ways off.

Marking as fixed since SVN trunk uses DN3.x
