The test is not sufficient, as it does not show that this happens when just using the EntityManager public API. What you are doing might not be a valid use of the internal API of UoW.

I've rewritten the test to use EntityManager instead of UoW. The issue is with the internal UoW state so the assert does check the UoW directly.

I can add additional test case that tests the side effect of not having the persistent collection present in the original data that would throw DUPLICATE INSERT in case the fix is not present if you'd prefer that, let me know :)

I added a second test case showing how dangerous this bug is. Both test cases fail without the fix.

@derrabus @beberlei Any possibility of getting this reviewed? We mitigated the issue by removing all collection reassignments and using ->clear() instead as proposed by @xificurk but it still remains dangerous.

@beberlei @derrabus @mpdude

Can this please get a review or at least close this MR with a reason why it's not a welcomed change? Thanks!

Sorry, I wasn't aware of this PR. Can you rebase onto 2.16.x please? We've changed a lot in the UoW recently and I'd like to see if the CI still passes.

The change made to UnitOfWork in this fix is breaking ManyToMany associations which are not persisted anymore: Collections are completely cleared on flush. (In my project at least)
I'm not sure what this is supposed to fix but the fact that it did not break any test is mind boggling.
Currently trying to find a way to reproduce this on a sample project.

EDIT: Nevermind this seems to be related to some custom code in my project, still I have a feeling that something is not right if a tiny change like this one can break a major feature.
