Why not go to WildFly 8.1 directly if you are already doing such big jump?

WildFly is renamed JBoss AS after version 7.

there ware lots and lots of fixes after 7.1.1 was released, go grab latest 8 Downloads · WildFly

btw, what you posted above there is no errors, just few warnings which are safe to ignore.
