      1. Enable "<access-log/>" inside undertow subsystem and make sure enable-http2="true" is specified on http-listener

              <subsystem xmlns="urn:jboss:domain:undertow:10.0" default-server="default-server" default-virtual-host="default-host" default-servlet-container="default" default-security-domain="other" statistics-enabled="${wildfly.undertow.statistics-enabled:${wildfly.statistics-enabled:false}}">
            ...
            <server name="default-server">
                <http-listener name="default" socket-binding="http" redirect-socket="https" enable-http2="true"/>
                <https-listener name="https" socket-binding="https" security-realm="ApplicationRealm" enable-http2="true"/>
                <host name="default-host" alias="localhost">
                    <location name="/" handler="welcome-content"/>
                    <http-invoker security-realm="ApplicationRealm"/>
                    <access-log/> <!-- add this -->
                </host>
            </server>
            ...
        </subsystem>

      2. Send the following HTTP/2 POST request by using curl which supports HTTP/2.

      curl --http2 http://localhost:8080/ -d "foo=bar"

      3. Check access-log.log

      Undertow access-log does not work for HTTP/2 POST request on HTTP Upgrade based connection. See also UNDERTOW-1745

      The web browsers basically do not support h2c via HTTP upgrade but only supports HTTP/2 through TLS ALPN. Also, most major Java HTTP clients do not support h2c via HTTP upgrade. As far as I know, "curl" supports it, though. So, I guess this issue has limited impacts.
