Accessing collection on PostLoad event causes LazyInitializationException
-------------------------------------------------------------------------

                 Key: HHH-5421
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5421
             Project: Hibernate Core
          Issue Type: Bug
    Affects Versions: 3.5.3
         Environment: Hibernate-3.5.3-Final
Oracle 11g
            Reporter: Stu White
         Attachments: hibernate-test.zip

We've encountered a problem using the PostLoad event to access a OneToMany Collection. 

Attempting to access the Collection in the PostLoad event handler results in a LazyInitializationException being thrown by AbstractEntityManagerImpl. The stack trace is below:

javax.persistence.PersistenceException: org.hibernate.LazyInitializationException: failed to lazily initialize a collection, no session or session was closed
	at org.hibernate.ejb.AbstractEntityManagerImpl.convert(AbstractEntityManagerImpl.java:1235)
	at org.hibernate.ejb.AbstractEntityManagerImpl.find(AbstractEntityManagerImpl.java:631)
	at org.hibernate.ejb.AbstractEntityManagerImpl.find(AbstractEntityManagerImpl.java:585)

I've attached a JUnit test case containing the classes and configuration. We're using Oracle 11g and Hibernate v3.5.3-Final, but the test case uses HSQLDB. 

If there is any further information I can provide to help diagnose this then please let me know.
