How to disable directory listing for Jetty's W

Question

I'm embedding Jetty (version 7.4.5.v20110725) into a java application. I'm serving JSP pages in ./webapps/jsp/ using Jetty's WebAppContext, but if I visit localhost:8080/jsp/ I get Jetty's directory listing for the entire contents of ./webapps/jsp/. I've tried setting the dirAllowed parameter to false on the WebAppContext and it does not change the directory listing behavior.

Disabling the directory listing on a ResourceHandler is simply done be passing false to setDirectoriesListed, works as expected. Can someone tell me how to do this for the WebAppContext?

import org.eclipse.jetty.server.Handler;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.handler.ContextHandler;
import org.eclipse.jetty.server.handler.HandlerList;
import org.eclipse.jetty.server.handler.ResourceHandler;
import org.eclipse.jetty.server.nio.SelectChannelConnector;
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.servlet.ServletHolder;
import org.eclipse.jetty.webapp.WebAppContext;

public class Test {

    public static void main(String[] args) throws Exception {
        Server server = new Server();
        SelectChannelConnector connector = new SelectChannelConnector();
        connector.setHost("127.0.0.1");
        connector.setPort(8080);
        server.addConnector(connector);

        // Create a resource handler for static content.
        ResourceHandler staticResourceHandler = new ResourceHandler();
        staticResourceHandler.setResourceBase("./webapps/static/");
        staticResourceHandler.setDirectoriesListed(false);

        // Create context handler for static resource handler.
        ContextHandler staticContextHandler = new ContextHandler();
        staticContextHandler.setContextPath("/static");
        staticContextHandler.setHandler(staticResourceHandler);

        // Create WebAppContext for JSP files.
        WebAppContext webAppContext = new WebAppContext();
        webAppContext.setContextPath("/jsp");
        webAppContext.setResourceBase("./webapps/jsp/");
        // ??? THIS DOES NOT STOP DIR LISTING OF ./webapps/jsp/ ???
        webAppContext.setInitParameter("dirAllowed", "false");

        // Create a handler list to store our static and servlet context handlers.
        HandlerList handlers = new HandlerList();
        handlers.setHandlers(new Handler[] { staticContextHandler, webAppContext });

        // Add the handlers to the server and start jetty.
        server.setHandler(handlers);
        server.start();
        server.join();
    }

}

You can set org.eclipse.jetty.servlet.Default.dirAllowed instead of dirAllowed:

webAppContext.setInitParameter("org.eclipse.jetty.servlet.Default.dirAllowed", "false");

Tested for Jetty 7.4.5.v20110725, 8.1.4.v20120524, 9.0.2.v20130417 and 9.2.0.v20140526.
