      I have just installed new JBoss-4.0.2 final (date=200505022023) and my web tier is suddenly broken. I didn't change anything and it was ok on all previous JBoss versions: 4.0.0, 4.0.2-RC1 and even recently taken from cvs 4.0.2 (date=200504260956) Branch_4_0.
      For the moment i rolled back to JBoss-4.0.2RC1 to be able to continue development.

      UserInfo class is present in both ka.jar and ka.war (as far as it's a model package class).
