I am trying to use HTTP 2 with Jetty 9.4.28.v20200408 and OpenJDK 1.8.0_252. I have followed the instructions in the docs, and it works fine.
If so, how can I add ALPN support to the HTTP2 module without using the ALPN module. I imagine it's possible by copying $JETTY_HOME/etc/jetty-http2.xml into $JETTY_BASE/etc and modifying it slightly. Is that right? If so, can you guide me a little?
