Gail Badner resolved HHH-3119.
------------------------------
Assignee: Gail Badner
Resolution: Rejected
This is expected behavior. When you call Session.clear() the session cache is cleared and all references to the Session object in proxies are set to null.
Hibernate.initialize(Object proxy) should be used to force initialization of the proxies and persistent collections of interest before calling Session.clear().

> Key: HHH-3119
> URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3119
> Project: Hibernate3
> Issue Type: Bug
> Components: core
> Affects Versions: 3.2.4, 3.2.4.sp1, 3.2.5, 3.2.6
> Reporter: Nick de Graeve
> Assignee: Gail Badner
> Priority: Blocker
> Attachments: hibernate.cfg.xml, HibernateTest.java, Level1.java, Level2.java, Level3.java

> We used to run JBoss 4.0.4.GA and we included Hibernate 3.2.0CR2 ourselves. Now we migrated to JBoss 4.2.2.GA and in that one Hibernate 3.2.4.sp1 is included by default.
> Unfortunately, we're getting LazyInitializationException when the object graph is more than 2 levels deep.
> E.g. RtTask --[OK]--> Priority --[FAIL]--> DictionaryEntry
> We haven't changed anything to our beans or configuration files.
> I did find out that v.3.2.4 is the first version that throws the exception.
