If User is loaded on server one, and placed into the session, if retrieved on server 2, an invocation of getSearchingPreferences() will throw the null pointer as the uuid of the hibernate session factory is serialised within the AbstractPersistentCollection, but refers to the factory on server one, not server 2.<br><br>The proposed solution from smarlow is to use the factory name over the id.</span> </td>
