The RabbitMQ server does not touch the message body. So this is either a 
problem with your code or, far less likely, the client library.

I cannot see anything obviously wrong with the snippet you sent, but 
since it's only a snippet the error is probably elsewhere. So please 
submit a complete, self-contained program that publishes and consumes a 
single byte[] message and exhibits the problem.
