Yes. https://webtide.com runs in that way (standalone server).

No, the code remains the same.
What you need to change is the classpath.
You don't need anymore alpn-boot in the bootclasspath, but you need:
* jetty-alpn-java-server-9.4.7.v20170914.jar
* alpn-api-1.1.3.v20160715.jar
in the classpath.
