> I am currently investigating the behavior of several MQTT brokers and noticed that the ActiveMQ broker responds to PINGREQ packets with PINGRESP packets even if no CONNECT packet has been sent before. 
> This would be a violation of MQTT-3.1.0-1 and MQTT-4.8.0-1 of MQTT v3.1.1 while MQTT v3.1 is not that strict about this issue, but does also state "When a TCP/IP socket connection is established from a client to a server, a protocol level session must be created using a CONNECT flow." (http://public.dhe.ibm.com/software/dw/webservices/ws-mqtt/mqtt-v3r1.html#connect)
> Since ActiveMQ supports MQTT v3.1 according to http://activemq.apache.org/,
> but also MQTT v3.1.1 according to Issue AMQ-4990, I am not sure whether this should actually be considered a bug.
