I’ve encountered an issue after upgrading to Hibernate 6.6.9.Final from 6.4.10.Final related to the behavior of
orphanRemoval = truewhen combined withFetchType.LAZY.Issue Description
In previous Hibernate versions, if I had a lazily-loaded collection with
orphanRemoval = trueand saved the parent entity without explicitly initializing the collection, Hibernate would not attempt to delete any orphans—unless the collection was explicitly modified.However, after updating to 6.6.9.Final, it seems that Hibernate attempts to remove orphans, even if the lazy collection was never loaded or accessed. This behavior is unexpected and leads to incorrect deletions.
The last version where this behavior worked as expected (i.e., the test passes) is 6.5.3.Final. From version 6.6.0.Final onward, this issue starts to occur.
