[jsr342-experts] Re: [jsr345-experts] Bean Validation aligment in EE 7 (was [jsr345-experts] Bean Validation support for EJBs?)

Antonio, Markus reminded me offline that it would be good to file a Jira issue
for this in our java.net project, so we make sure we don't forget it even if we
can't do it in EE 7. Can you do that please? Thanks!

And yes, we should all be doing a better job filing issues in Jira! Note that I
don't believe Jira is the right place to have a long discussion about an issue
(that's what the mailing list is for), but it is the right place to track an issue.
