[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3799) PersistentSet does not honor hashcode/equals contract when loaded eagerly
[
https://hibernate.onjira.com/browse/HHH-3799?page=com.atlassian.jira.plug...
]
Nate Clark commented on HHH-3799:
---------------------------------
Shawn, if I understand your scenario correctly, the PK is the Hibernate ID, and the UUID
is a persistent, non-ID property. Why not use PK.hashCode() as the hashCode() of the
containing object, and leave the UUID out of hashcode calculation? Wouldn't that make
you immune to the problem described here?
I think any challenges relating to the lack of an ID in an uninitialized entity are
unrelated to this issue - please correct me if I'm mistaken.
PersistentSet does not honor hashcode/equals contract when loaded
eagerly
-------------------------------------------------------------------------
Key: HHH-3799
URL: https://hibernate.onjira.com/browse/HHH-3799
Project: Hibernate ORM
Issue Type: Bug
Components: core
Affects Versions: 3.3.1, 3.5.1
Reporter: Igor Vaynberg
Assignee: Gail Badner
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.
