Yes.

Publishing is asynchronous, which means basic.publish itself will never 
"return" any error that it may have triggered. Instead the error is 
handled asynchronously by the client library code. The 
AlreadyClosedException you are seeing is due to library having received 
and processed the server-initiated channel.close already by the time the 
application tries to close the channel.
