When I try to deploy one of the pre-built WAR files from GitHub, the application root shows a directory listing instead of sending me to the index page. I have tried 1.9.1, 1.9.2, and 2.0.8, with the same results.
If I manually add eg /private to the URL, then it works and takes me to the login screen.
My application server is Jetty 9.4.57, but with no special configuration, just setting the context path, WAR file location, and applicationPath.
