You don't need to write your own ALPN processor.

You just specify jetty.alpn.protocols=acme-tls/1, http/1.1.

A connection attempt that carries the TLS ALPN extension of
"acme-tls/1" will complete the TLS handshake, but then it won't find a
ConnectionFactory, so the connection will be closed.

A connection attempt that carries the TLS ALPN extension of "http/1.1"
will complete the TLS handshake, find the HttpConnectionFactory, and
proceed handling HTTP requests that arrive on the connection.
