T5.0.7: ThreadCleanupHubImpl.cleanup swallows exceptions

[Franz Amador]

ThreadCleanupHubImpl.cleanup (line 53) catches exceptions thrown by service 
initialization cleanup.  It logs them, which is good, but it doesn't pass them 
up, which is causing me problems.  I want to know if Hibernate initialized 
successfully, but this prevents me from seeing exceptions thrown during the 
transaction commit in HibernateSessionManagerImpl.threadDidCleanup.  Is this an 
oversight or is there a design goal of having the Registry come up no matter 
what?
