[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3799) PersistentSet does not honor hashcode/equals contract when loaded eagerly

Florimon van Putte commented on HHH-3799:
-----------------------------------------
I am also confirming the bug and voting +1.
We have an entity with both multiple parent and multiple child relations to itself, and
when we just load the whole graph, many child instances are missing, because our
hashCode() and equals() depend on a field which isn't loaded yet by hibernate when it
constructs the persistent sets.
Because of this we have to make our hashCode() and equals() depend on the 'id'
field only, which isn't an ideal situation either.
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
Fix For: 3.5.x
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.
