      Install a new server instance, start it with Java 8u20, and try to create a new user with add-user.bat.

      Description

      The server can be successfully started, but I'm unable to manage it because running add-user.bat immediately fails with the following error:

      Exception in thread "main" java.lang.UnsupportedClassVersionError: org/jboss/as/domain/management/security/adduser/AddUser : Unsupported major.minor version 51.0
