Hi,

I am getting exception when executing following code:

{code}
@Entity
@Audited
public class M2MIndexedListEntity {
    ...

    @ManyToMany(cascade = CascadeType.ALL)
    @OrderColumn(name="sortOrder")
    @Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)
    private List<NotAuditedEntity> list = new ArrayList<NotAuditedEntity>();
}

@Entity
public class NotAuditedEntity {
...
}
...
M2MIndexedListEntity entity = (M2MIndexedListEntity) auditReader.createQuery()
   .forRevisionsOfEntity(M2MIndexedListEntity.class, true, false)
   .getSingleResult();

assertEquals(1,entity.getList().size());

{code}

Stack trace is the following:
{code}

java.lang.ClassCastException: testapp.NotAuditedEntity cannot be cast to java.util.Map

	at org.hibernate.envers.entities.mapper.relation.lazy.proxy.CollectionProxy.size(CollectionProxy.java:55)
	
{code}

I've attached a full test case. Unzip it, run *mvn test* and see test failing
