Jetty 8 is EOL (End of Life) https://dev.eclipse.org/mhonarc/lists/jetty-announce/msg00069.html
Without knowing how the Android Studio instance of Jetty was started, it would be hard to troubleshoot. If this was a distribution started version of Jetty, then its likely missing a distribution option to enable (and configure) for JSPs.
