i'm curious, when you installed jboss as 4.3 did it ask for specifying username and password or not ? and what entry in jmx-console-users.proeprties was commented ? It should just work out of the box so i'm just trying to identify if 4.3 have a bad change or this is just normal since a 4.3 installed by the AS installer is secured by default.
