AR commented on AMQ-5358:
-------------------------
I believe there is still an issue here. The MQTT spec clearly says that the
message should be stored if it is published with QoS >0. In other words, it
does not depend on the subscription QoS.
This means that even if client1 made a durable subscription with QoS 0 and if
client2 published a message with QoS >0, then client1 should receive it. In my
observation, this did not happen and is not compliant with the spec.
Please verify.
