ManyToMany with CascadeType ALL => StaleStateException
------------------------------------------------------
Key: ANN-596
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-596
Project: Hibernate Annotations
Issue Type: Bug
Affects Versions: 3.3.0.ga, 3.2.0.cr2
Environment: Hibernate 3.2.0cr2 with Annotations 3.2.0.cr2; and Hibernate 3.2 with Annotations 3.3.0ga.
Spring 2.0.4
HSQL 1.8.0 and MySQL 5.0
Reporter: Steven Morrison
Priority: Minor
Attachments: HibernateManyToManyMappingError.zip
Originally posted as bug to forums (http://forum.hibernate.org/posting.php?mode=editpost&p=2345494), but received no response.
[b]Description:[/b] Hibernate appears to be end up in an inconsistent state when working with a many-to-many mapping using cascade = ALL.
The test below shows Hibernate persisting a Root (with a Value mapped as many-to-many), then later deleting the Root (which also deletes the Value). When attempting to delete the Value, hibernate's "listing entities" logging suggests that the Value instance is still persisted, but the Root deletion has removed this. StaleStateException is then thrown.

[b]Question:[/b] Is this a bug in Hibernate? My understanding is that Hibernate's state becomes different to that of the DB, though all deletions are explicitly mentioned in DEBUG logging.
