| So your issue on 5.1.x is related to the fix for HHH-11582 Closed . In short previously we were taking the modified flags from the merge-action only rather than accounting for the fact that the modified flags from the persist-action should also be considered. With the fix we overlay the modified flags from the persist-action over those from the merge-action so we have a consistent view of what fields were modified in that transaction. I will talk with Gail but I think should she not want to backport this, you could consider patching 5.1 with the fix. For reference, here is the commit you'd specifically need to add for AddWorkUnit for hibernate-envers https://github.com/hibernate/hibernate-orm/commit/f9c1e7e3394b10bac01181cf034fa0085dff261f |
