Hello @Andrea Boriero, thank for the fix but if I’m not mistaking, it seems that you have fixed https://hibernate.atlassian.net/browse/HHH-16810 instead of this one ( HHH-16821 Closed ) as the test cased used (EmbeddableWithManyToManyAndOptimistickLockingDeletionTest) is the one from https://hibernate.atlassian.net/browse/HHH-16810

I have tested shouldDeleteProduct on the 6.2.6.Final and the issue is still present.
