Timothy Bish commented on AMQ-5880:
-----------------------------------
This is caused by a bug in the FuseSource MQTT client codecs used in the
protocol converter. I've committed a fix there for this but a new release is
needed before this will be fixed broker side.
> AMQ does not accept long (>32kb) MQTT topic filters in SUBSCRIBE
