I was trying to do exact same thing but it didn't work for me. So, I logged a ticket, which seems to be fixed.
But, I am still not able to deploy my EAR that has one RA and one MDB connecting to the RA.
Please see my detail comment in the ticket here: https://issues.jboss.org/browse/AS7-2505?focusedCommentId=12653211&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-12653211
Please somebody suggest -- what am I doing wrong?
Takayoshi Kimura, did it work for you?
