In keeping with
http://jira.jboss.com/jira/browse/JBAS-1434
Validation of JMS Activation Spec should be implemented. This should be done for both EJB2.0 and EJB2.1 deployments as well as devising a stragety for what exactly the RA should do in the case of validation failure.
Of course validation can mean many things. If anyone has any thoughts on this let me know.
Also, this should probably be done for the MailAdapter as well.
