• When I install EAP and access http://localhost:8080/ welcome page is returned. - OK
• When I deploy my custom web application with the app defined for root context => in jboss-web.xml there is defined <context-root>/</context-root>, after accessing http://localhost:8080/ the content of my application is returned. - OK
• When I undeploy the previously custom application used as default welcome page and try to access http://localhost:8080/, the 404 is returned (I would expect 200 is returned with the original welcome page defined by the welcome-file handler.

Note: Reloading the server configuration makes the original welcome page again accessible.
