If it was acceptable for ordering to be lost after rollback that makes my life a lot easier. This JIRA task seems to imply that it is not a requirement of the spec. http://jira.jboss.com/jira/browse/JBAS-2444 Although I don't really understand how it is not a requirement since the spec says that session recovery occurs on rollback, and session recovery maintains the order (if prioriry and expiration are taken out of the equation).
