This link https://access.redhat.com/documentation/en-us/red_hat_amq/7.2/html/deploying_amq_broker_on_openshift_container_platform/config-client-conns_broker-ocp refers to old activemq-client style (failover+ssl schema in client uri). But the documentation of supported AMQ clients says in first place, that we should use AMQP client (https://access.redhat.com/documentation/en-us/red_hat_amq/7.2/html/amq_clients_overview/components).
So the documentation should show example for the new AMQP client.
