[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3309) Serialize/Deserialize problem in AbstractLazyInitializer with entitymode.MAP.

[Steve Ebersole (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3309?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_30606 ] 

Steve Ebersole commented on HHH-3309:
-------------------------------------

This is trying to fix a symptom.  The underlying issue is that AbstractLazyInitializer includes code to replace itself in the serial stream during serialization (using the standard serialization writeReplace approach).  For whatever reason, it would appear that writeReplace is not being called on Proxies (just in EntityMode.MAP entity-maps???) when run on JDK6.

So something changed wrt to serialization on JDK6.  We'll have to investigate what.

This fix is simply allowing the serialized initializer to be deserialized; however, as outlined above, it should never have been serialized in the first place.

> I am work with entitymode.MAP and Spring Web Flow. When SWF trying to serialize the Map Class, then you would get a java.io.InvalidClassException: no valid constructor. I created a no argument constructor 	AbstractLazyInitializer(), then i build hibernate with JDK 1.5 and this work fine for me in JDK 1.6.
