Description

Hello, I noticed an unexpected MQTT path separator conversion handling. (May be I'm missing some configuration parameter in the acceptor definition?)

The char '.' on a MQTT topic is handled by Artemis as a topic separator instead of a "normal" topic character. So an MQTT topic like 'a.b.c.d' becames 'a/b/c/d'.

I attach a Junit test I developed for testing different topics.

I used Artemis 2.9.0. The acceptor configuration is:

tcp://0.0.0.0:1883?tcpSendBufferSize=1048576&tcpReceiveBufferSize=1048576&protocols=MQTT&allowLinkStealing=true&useEpoll=true

 

Regards,

Riccardo
