Description

Hi,

using a router configuration file in the JSON format with something like this :

["address", {
    "prefix": "telemetry/",
    "distribution": "multicast"
  }],

  ["address", {
    "prefix": "event/",
    "distribution": "multicast"
  }],

the router crashes on startup with following error :

[root@512788e6bda1 /]# qdrouterd -c /etc/hono/qdrouter/qdrouterd.json

It doesn't happen using the deprecated "fixedAddress" entity.
