      Use add-user script to add some user to ManagementRealm Start server with standalone.xml Go to http://localhost:9990 and try to authenticate with empty username -> exception will occur in server log and Internal Server Error (status 500) is returned

      In case when empty username is passed during authentication to Management Console then exception is thrown to server log and Internal Server Error (status 500) is returned to user (which leads to displaying "Connect to Management Interface" page. User is not able to try to login again.

      In WildFly 10.1.0 this scenario works fine - after passing empty username during authentication, authentication failed and login window is displayed again. I request blocker due to regression.

      Exception thrown to server log:
