> If you query an entity that has a list with (@IndexColumn and Eager) and this list is empty there is an Exception.
> It appears that the code is verifying that the index column it not null, but in this case the index column is null because the left join will bring back a null because the list empty...
> The stack Trace:
> 	org.hibernate.HibernateException:null index column for collection: <<EntityClass>>
