Matej Novotny commented on RF-13603:
------------------------------------

Verified, I managed to reproduce this issue.
I used kitchensink archetype (5.0.0.Alpha3) which I built with JDK 6 and deployed to JBoss AS 7.1 (again using Java 6). Even without changing the web.xml file I am getting very similar compatibility error (this one comes from Skinbean, but there are more such errors in log, all of them throwing UnsupportedClassVersionError).

I will modify steps to reproduce accordingly to my findings. If there is anything else I can do, let me know.
