There are some side effects with the patch:

1) if the entire result set is not scrolled, then an exception occurs on session flush;
2) when the block of rows is processed for the current entity, the row following the block (for the next entity) is also processed; an exception is thrown if the join fetched collection for that next entity is accessed.

I've created a pull request with a different fix.

Please try it out and let us know if it works for you.

Thanks,
Gail
