It might be a good idea to make the failure more obvious here. Maybe something like:

    The invocation of `appTwo` throws a  `java.lang.reflect.InvocationTargetException` since the secured method is called and there is no Role for the user defined.  You get a `BUILD FAILURE` and the client outputs the following information:

        [ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:java (default-cli) on project jboss-as-ejb-multi-server-client: An exception occured while executing the Java class. null: InvocationTargetException: JBAS014502: Invocation on method: public abstract java.lang.String org.jboss.as.quickstarts.ejb.multi.server.app.AppTwo.invokeSecured(java.lang.String) of bean: AppTwoBean is not allowed -> [Help 1]
[ERROR] 

    Update the user `quickuser1` and `quickuser2` and give them one of the Roles `AppTwo` or `Intern`.
