Subject How work around OpenJPA-1365

OpenJPA-1365: DISTINCT keyword has no effect with JOIN FETCH queries

We're porting a formerly JDO based application to JPA.
We wanted to heavily use JOIN FETCHs to reduce the number of SQL statements generated.
We do not know how to get rid of those weird duplicates produced by a JPQL statement including
join fetch clause.
We urgently need a solution or work-around for this problem, because we don't see another
way to
get our app fast enough with OpenJPA.

How can we work-around this problem?

Does anybody know the status of the issue OpenJPA-1365? Is anybody working on it?

kind regards,
