ScrollableResults does not fetch many-to-many collections
---------------------------------------------------------

                 Key: HHH-5057
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5057
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.3.2
            Reporter: Jérôme Van Der Linden
            Priority: Blocker


I have a many-to-many relation between two objects :

{code:title=Project.java|borderStyle=solid}
@Entity
public class Project {
  private List<Viperson> managers;

  @ManyToMany(targetEntity = Viperson.class)
  @JoinTable(name = "PRJMANAGER", joinColumns = @JoinColumn(name = "PROJECTID", nullable = false), inverseJoinColumns = @JoinColumn(name = "VIPID", nullable = false)) 
  public List<Viperson> getManagers() {
    return managers;
  }
}
{code}

{code:title=Viperson.java|borderStyle=solid}
@Entity
public class Viperson {
  private List<Project> projects;

  @ManyToMany(mappedBy = "managers", targetEntity = Project.class)
  public List<Project> getProjects() {
    return projects;
  }
}
{code}

And the following test (actually, it is a code from spring batch HibernateCursorItemReader I put in a testcase) : 
{code}
@Test
public void testSelectAll() {
  StatelessSession statelessSession = sessionFactory.openStatelessSession();
  ScrollableResults cursor = statelessSession.createQuery("from Project").scroll();
  Object[] data = null;
  if (cursor.next()) {
    data = cursor.get();
  }
}
{code}
data contains a {{Project}} but {{managers}} field is *null*, +even if I add eager fetching+. I have also a {{OneToMany}} in the {{Project}} class. This one is well loaded (i have a {{PersistentBag}}).

Is there anything I miss ? I suspect a bug on that.
