>             Project: Hibernate Core
>          Issue Type: Bug
>          Components: query-hql
>            Reporter: Steve Ebersole
>            Assignee: Steve Ebersole

> Consider:
> select ( select clasn1.name from riskClasns_Contxt0.clasn as clasn1 ) as policyType
> from Risk as risk0
>     inner join risk0.riskClasns_Contxt as riskClasns_Contxt0
>     inner join riskClasns_Contxt0.clasn as clasn0
>     inner join clasn0.clasnScheme as clasnScheme0
> Currently we miss the conditions needed in the subquery because we reuse the from element corresponding to riskClasns_Contxt0.clasn from the outer query.
> Again the solution is to recognize that each has a different alias indicating that we should not reuse the FromElement from the outer query here.
> alias matching here needs to consider null as never matching
