    I actually was talking about it with @bbende . I actually did it on purpose 
to ensure that it doesn't collide with something that may not actually be AMQP 
property (e.g., 'amqp.message.sender=Mark Payne'). So it a way I've chosen a 
special character to limit the possibility of outside interference.

> David Smith in the mailing list has already begun work on this.  The link to 
> his current set of code in Github is here:  
> https://github.com/helicopterman22/nifi_amqp_processors
> He is seeking help with licensing/unit testing/etc.. so that it can end up in 
> a build.
> We have word from another user now that they too are interested in this.  
> They specifically are using RabbitMQ but we should be able to implement 
> (ideally) a pure AMQP protocol friendly version and be good to go.
