Igor Vaynberg commented on HHH-3799:
------------------------------------
i wouldnt necessarily agree that the workaround is easy to implement.
the implementation is technically easy, but it sure as hell hard to find all the queries
that have the potential to retrieve any entity that makes the affected container entity
reachable.
eg FROM Entity e LEFT JOIN FETCH e.foo.bar.baz.container where as before all you had was
FROM Entity e
PersistentSet does not honor hashcode/equals contract when loaded
eagerly
-------------------------------------------------------------------------
Key: HHH-3799
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3799
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.3.1
Reporter: Igor Vaynberg
Assignee: Gail Badner
Priority: Minor
Attachments: test.zip
when persistent set is loaded eagerly in some situations it calls hashcode on its items
before their field values are populated and then uses this incorrect hashcode to store
them in the set. this makes set items inaccessible by any collection items that rely on
hashcode such as contains(), remove(), etc.
attached is a simple maven test project that reproduces the error, unzip and mvn test to
run the test.
