This commit introduces MessagingExceptionTranslator, a messaging exception translation infrastructure similar to what PersistenceExceptionTranslator provides. JmsMessagingTemplate does not throw raw JmsException anymore but translates those to an instance of Spring's MessagingException hierarchy. Issue: SPR-12038pull/602/merge
