Justin Bertram commented on ARTEMIS-3913:
-----------------------------------------
As noted previously, the broker will send a {{CONNACK}} with a reason code of
{{134}} _if and only if_ the client is using MQTT *5*. This is true of every
broker since support for MQTT 5 was implemented in 2.21.0. This, of course,
includes 2.23.1.
> MQTTReasonCodes byte loss of precision，must int type
