[hibernate] criteria.list() return rendundant records if fetchtype is EAGER

Question

Hi all, look this code:

// In A.java class
@OneToMany(mappedBy="a", fetch=FetchType.EAGER)
@Cascade(CascadeType.SAVE_UPDATE)
private List<B> bList;

// In B.java class
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="id_a")
@Cascade(CascadeType.SAVE_UPDATE)
private A a;

And this is my record in DB tables.

    // Table A
   |  ID  |   other column . . .   |
   |  1   |       . . .            |

   //Table B
   |  ID  | ID_A  |   other column  . . .  |
   |  1   |   1   |        . . .           |
   |  2   |   1   |        . . .           |

Now, i try to build a criteria to obtain all A records, int his case one!

List<A> aList=session.createCriteria(A.class).list();

The problem is this code return two rendundant records! One foreach record in B.

How can i resolve without change my fetchtype to LAZY?

Thanks.
