Re: [jboss-as7-dev] Clustering tests

Kabir, what exactly is admin mode? Is it the same server profile but with controls on communication from clients? The problem is that you're replacing a dead server (no communication channels) with a live server in admin mode (with live communication channels). So IIUC, you depend on the admin mode working correctly to block communications from the outside. Also, if JGroups detected failed group members using a standard OS ping mechanism (which it doesn't), then this could change JGroups view of failed vs non-failed hosts - that is, if admin mode did not also block pings.
