* *Describe the bug* *
I am currently upgrading a project from hibernate 5.0.10 (wildfly 10), to hibernate 5.4.17 (quarkus).
The application itself works without any problems.
Test execution fails however on the new hibernate version.

I reduced the problem down to some strange session handling.
Inside "AbstractPersistentCollection.setCurrentSession", the sessions are not equal. The collection was created with the entitymanager (and therefore session) I use in my test, but the transaction commit happens with another session.

I attached an minimal reproducer project, which has hibernate 5.4.17 as dependency.
You can relativly easily switch it to 5.0.10, where the tests execute correctly.

* *Expected behavior* *
No problems with test execution after the upgrade to hibernate 5.4.17.

* *Actual behavior* *
When I run my tests, I get the following exception. The test run is failed (red) in this case.
