Description

AMQ accepts: "#MQTTClient" , "MQTTClient/#/def", "MQTTClient+"

MQTT spec says:
[MQTT-4.7.1-2]
The multi-level wildcard character MUST be specified either on its own or following a topic level separator. In either case it MUST be the last character specified in the Topic Filter.
[MQTT-4.7.1-3]
The single-level wildcard can be used at any level in the Topic Filter, including first and last levels. Where it is used it MUST occupy an entire level of the filter.
