Description

The ConsumerNetworkThread runs a tight loop infinitely.  However, when encountering an unexpected exception, it logs an error and continues.

 

I think this might not be ideal because user can run blind for a long time before discovering there's something wrong with the code; so I believe we should propagate the throwable back to the polling thread.
