A query like "select e.collec from MyObj e where e.id = 1" will retreive the collection linked to MyObj when Hib. request directly the database, but returns a Collection of null pointers when using the Query cache.
The content of the query cache is [timestamp, null, null, ...] instead of [timestamp, id1, id2, ...]

@Entity
public class MyObj {
  @Id private Integer id;
  @OneToMany List<MyObj2> collec;
...
}

@Entity
public class MyObj2 ....
