Another question raised here, I think we need to handle the exceptions thrown by blockingQueue.add. I'm looking at the RaftMessageQueue impl, the exceptions aren't being handled there, are we expecting the caller/client to handle these exceptions? -- This is an automated message from the Apache Git Service.
