Description

If message body size exceeds specified threshold, client would try to compress the message body.

Here there are two issues: 1) current implementation changes message body directly, which is not a good practice; 2) if asynchronous send method is employed to deliver message, when onException is invoked, the callback may capture the compressed message body before the finally block restores it.
