Gary Tully commented on ARTEMIS-3223:
-------------------------------------
the fix for ARTEMIS-1612 needs to be reworked, with the current address model,
prefixed queues do not exist on the broker, they are an artefact of an acceptor
that does transformation. Transformation of the routing needs to be reflected
in the message address such that further routing (and redistribution) can work
without knowledge of the prefix.

> Key: ARTEMIS-3223
> URL: https://issues.apache.org/jira/browse/ARTEMIS-3223
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: MQTT
> Affects Versions: 2.16.0, 2.17.0
> Environment: *Clients*
> * For testing
> ** mosquitto_sub 1.4.15 (receiving client)
> ** mosquitto_pub 1.4.15 (sending client)
> * Also happens with these clients
> ** PAHO Java MQTT3 Client
> ** HiveMQ Java MQTT3 Client (throws "Malformed topic" exception)
> *Broker*
> We first noticed the problem with version 2.16.0, and it still exists in
> 2.17.0. We're running Artemis in docker using vromero/activemq-artemis

> This is a similar problem to ARTEMIS-2888 - if MQTT messages are
> redistributed after a client has reconnected and the subscription contains
> wildcards, the topic of the message contains the wildcard address, not the
> specific address the message was addressed to.
> *Note*: Addresses are written in JMS form (x.y.z) instead of MQTT form
> (x/y/z).
> *Step to reproduce*
> # Connect the receiving client to node 1 with a durable session (aka
> clean-session false) and subscribe to a topic containing wildcards, e.g.
> *test.+.test1*
> # Send a test message using another client to any node to topic
> *test.1234.test1*. It should be delivered correctly.
> # Disconnect the receiving client.
> # Send a test message to each individual node of the cluster (containing a
> unique payload for making them identifyable).
> # Reconnect the receiving client to node 2 (it should work with any of the
> nodes, even the previously used node 1).
> # The receiving client will receive all messages. But only the messages of
> the node the client is currently connected to will contain the correct topic.
> All other messages will contain *test.+.test1* as the topic.
