We found this problem in new code we wrote not so long ago so it's very possible the bug existed before 4.3.3. It's not a pattern we usually use.

One of my coworker found that on the Hibernate forum: https://forum.hibernate.org/viewtopic.php?f=1&t=1030597 and it looks like the same problem.

As they are talking about 4.1.7, I suspect it's an old bug.
