My experience is with EJB3/JPA/Hibernate on Weblogic Server 10.1 and 10.3... I noticed earlier in this chain that you were manually handling transactions (begin/commit) I think. If Spring supports container-managed transactions (CMT), the begin/end is handled by the transaction and in our implementation, the session doesn't close until all pending 'operations' on the persistence layer are complete (ie. Lazy inits)
Not sure this is exactly your problem.
