NOTICE: Webswing now uses Jetty 12 as its default embedded server.
In response to Jetty 9.4 reaching End of Life (EOL) and no longer receiving security patches, Webswing has upgraded its default embedded server to Jetty 12. However, Jetty 12 now requires Java 17 or higher. When running Java < 17, Jetty 12 cannot be used. There is an automatic fallback to an embedded Tomcat server to maintain compatibility.
