[SECURITY] Fedora 26 Update: jetty-9.4.6-1.v20170531.fc26

Jetty is a 100% Java HTTP Server and Servlet Container. This means that you do not need to configure and run a separate web server (like Apache) in ord er to use Java, servlets and JSPs to generate dynamic content. Jetty is a fully featured web server for static and dynamic content. Unlike separate server/container solutions, this means that your web server and web application run in the same process, without interconnection overheads and complications. Furthermore, as a pure java component, Jetty can be simp ly included in your application for demonstration, distribution or deployment. Jetty is available on all Java supported platforms.
