When subscribing to an MQTT topic, "+" and "#" can be used as wildcards (more details).
This works with Quarkus 1.4.2-Final but stops working when switching to Quarkus 1.5.0-Final. It still fails in Quarkus 1.5.2-Final.

cd quarkus-1.5.0-mqtt-wildcard-problem

mvn clean quarkus:dev
Every 5 seconds a line "Sending price" appears.
In another shell:
curl localhost:8080/prices/stream
Result (as expected):
- Every 5 seconds a number appears in CURL's output.
- In the Quarkus output, each "Sending price" line is now followed by "Receiving price".
Press CTRL+C to stop Quarkus.

BUT: MQTT subscription topic wildcards should not stop working with Quarkus 1.5!
