I came across this strange bug while implementing lazy loading using Bytecode enhancement in our application. At some point in our code, we do the following operations in a single session:
(obviously very simplified)
With relevant Entities:
The Code works fine with bytecode enhancement in Version 5.2.12. In higher Versions of Hibernate the code fails on the second flush with an Exception:
org.hibernate.HibernateException: A collection with cascade="all-delete-orphan" was no longer referenced by the owning entity instance: hibernate.model.SubItem.superAssociation
If we turn off bytecode enhancement, it works fine in all the versions I have tried.
See the attached Test Case for the concrete example.
java version: 1.8.0_92
maven version: 3.6.1
OS: Windows 10
DB: Derby (10.12.1.1), Oracle DB 19c
Still experiencing the same problem in version 5.4.12. What’s the status on this?
We’re also experiencing this issue. Is there any progress to report? We’re on version 5.4.6.
