Not sure I follow your configuration.

Does this mean you are, or are not, using slf4j + log4j?

So the Exception is logged at WARN level, but it's no longer an Exception?

I don't understand what you are saying or asking.

==============

import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.webapp.WebAppContext;

public class QuickStartServer {
    public static final int PORT = 8080;
    public static final String CONTEXT = "/xx";

    public static void main(String[] args) throws Exception {
        Server server = new Server(PORT);
        WebAppContext context = new WebAppContext();
        context.setDescriptor("src/main/webapp/WEB-INF/web.xml");
        context.setResourceBase("src/main/webapp");
        context.setContextPath(CONTEXT);
        context.setParentLoaderPriority(true);
        server.setHandler(context);
        server.start();
        System.out.println("server started");
        server.join();
    }
}

I found if log4j or slf4j  exists
the Exception will turn to  WARN  o.e.jetty.servlet.ServletHandler ,
not Exception?
can somebody explain the behaviour?
