[rabbitmq-discuss] Shovel with multiple publish_properties oddity

Fri Dec 20 16:37:31 GMT 2013

I just had a quick look at this.

Believe it or not the shovel config parser seems to be sensitive to the 
order of publish_properties. I was able to make this work by putting 
content_type before delivery_mode.

The developer responsible will receive a kicking.

With seasonal good cheer to all, Simon
