Thanks Tomaz, for your reply.
There are no plans of upgrading from 7.1.1. to upper versions.
My concern is about stability between 7.1.1 and 7.0.2 as my application team is suggesting to degrade JBoss to 7.0.2 instead as they observed application is much faster in 7.0.2. Please advice.
I think this depends mainly on your environment and your definition of "stability".
But maybe this blog gives you some more ideas on how to approach this question The curious case of JBoss AS 7.1.2 and 7.1.3 | henk53
According to Rupert "Jboss 7.0 is then actually EAP 6 beta 1, 7.0.1 is beta 2, 7.1.0 is beta 3 and 7.1.1 is rc 1."
Taking this as given then I would deem 7.1.1 (rc 1) as more stable than 7.0.2 (still beta release).
