Ingo Jobling commented on HHH-1751:
-----------------------------------

I am confirming this bug.  Until this is fixed, I modified my HQL by removi=
ng the fetch join on "one to many" collection (resulting in n+1 selects).

This seems to be the same bug as HHH-1283 ScrollableResults JoinFetch don't=
 set child collection correctly=E3=80=80after the second parent object

> When scrolling a query that has a jon fetch on a collection (set), the co=
llection is not loaded correctly. It appears that only the first item in th=
e collection is correctly loaded.
> Th attached tests show this behaviour, as well as a number of orderings i=
n the query to show how the collection is corruptly loaded.
