Moving the forum discussion http://www.jboss.org/index.html?module=bb&op=viewtopic&t=155074&a... to this mailing list. Currently, whenever a MC bean is deployed, a corresponding MBean too gets registered. This MBean provides more of debug information than anything else. As part of https://jira.jboss.org/jira/browse/JBAS-6987 and as discussed in that forum thread, i am planning to disable the MBean registration by default (users can enable it, if required). This might bring in some minor performance improvement too. Let me know if anyone has any objections to this change. I'll changing this in AS trunk. -Jaikiran
