I'm not sure if this is still about the same topic: You mentioned first that it's about unencrypted traffic between httpd and tomcat, now Chrome56 comes into the game. According to https://en.wikipedia.org/wiki/HTTP/2#Encryption, Chrome won't initiate any unencrypted HTTP/2 connection and I'm not sure if this is what you're testing/bypassing Apache with in order to just test the connector.
