<p>Why are we seeing an unexpected result set entry for the previous comment (failing case) that we don't see when <a href="https://hibernate.onjira.com/browse/HHH-6361" title="Collection events may contain wrong stored snapshot after merging a detached entity into the persistencecontext"><del>HHH-6361</del></a> is not used. What are the possible reasons? Note that the first line of TRACE logging shows that a new EntityManager/Session will be used (as per the "created entity manager").</p>
<p>Clearly, this problem has more to do with the previous activity when we are doing the createRelationships() setup (which is also when the <a href="https://hibernate.onjira.com/browse/HHH-6361" title="Collection events may contain wrong stored snapshot after merging a detached entity into the persistencecontext"><del>HHH-6361</del></a> introduced code is invoked).</p></div>
