>             Project: Hibernate ORM
>          Issue Type: Bug
>    Affects Versions: 3.6.6
>            Reporter: Christian Beikov
>            Assignee: Gail Badner
>            Priority: Critical

> The problem is discussed on the forum a long time ago. I just found the topic and i wanted to report that this bug is still available in 3.6.6
> https://forum.hibernate.org/viewtopic.php?f=1&t=987905&start=0
> Here a concrete example from my usecase:
> class A{
>  private B b;
> }
> class B{
>  private Map<String, C> map;
> }
> class C{
>  private String c;
> }
> Just imagine that the classes and fields would be annotated right ;)
> Now the problem in my case was that i wanted a list of A elements with fetch joined B and of course it's map.
> I tried the following query:
> FROM A a LEFT OUTER JOIN FETCH a.b bElem LEFT OUTER JOIN bElem.map cMap
> and i got a NullPointerException just like the users which posted in the given topic.
> My workaround was:
> FROM A a LEFT OUTER JOIN FETCH a.b bElem LEFT OUTER JOIN a.b.map cMap
> The main problem now is, that i have a dynamic fetch profile system which won't work correctly if this issue is not solved.
