==== Using DISTINCT with entity queries
Starting with Hibernate ORM 6 it is no longer necessary to use *distinct* in JPQL and HQL
to filter out the same parent entity references when join fetching a child collection.
The returning duplicates of entities are always filtered by Hibernate.
Which means that for instance it is no longer necessary to set `QueryHints#HINT_PASS_DISTINCT_THROUGH` to `false`
in order to skip the entity duplicates without producing a `distinct` in the SQL query.
From Hibernate ORM 6 a `distinct` is always passed to the SQL query and the flag `QueryHints#HINT_PASS_DISTINCT_THROUGH`
has been removed.
