We can't encourage building systems that randomly goes of an reopens, reconnect, reaccess the database when you have just explicitly closed the access. It's just not a good idea!

Furthermore it won't ever work for collection wrappers, only for proxies. 

You should/could instead reassociate the objects/proxies with a new session by using saveOrUpdate() or even better lock(o, LockMode.NONE); which will reattach the object without performing any save or updates.

Description:
For discussion, please see the following forum topic:
http://forum.hibernate.org/viewtopic.php?t=42

In summary, there are scenarios in which it one may want proxies to be resolved in a different session.

The attached patch adds a ThreadLocal to SessionFactoryImpl which keeps track of the last opened session. If a the session that created a proxy is closed when it comes time to initialize the proxy, the last opened session is used instead, unless it has been closed as well.
