We configure pax HTTP port to be the same as HTTPS port.  Previously this worked and only HTTPs would come up.  However with changes to Oxygen this now is seen as a port conflict by Pax and REST fails to come up at all.  The solution is to explicitly disable http when TLS is enabled via Pax config.  Also, there is a duplicate configuration for http port in the pax config file due to  a missing regex match when setting the file_line.
