dpocock updated WFLY-3068:
--------------------------

          Description: 

If I try to start Wildfly with Java 6 (which is no longer support of course) it just fails with a stack:

It would be more friendly if it checked the Java version in the main() function and stopped gracefully.  The stack trace is not hard to understand but may not be obvious to everybody.

             Priority: Minor  (was: Major)
    Affects Version/s: 8.0.0.Final
          Environment: Java version < 7
          Component/s: Server
