> When a server implementation throws an exception handling an RPC, the Handler thread
catches it and logs it before responding with the exception over the IPC channel. This is
currently done at INFO level.
> I'd like to propose that, if the exception is an unchecked exception, it should be logged
at WARN level instead. This can help alert operators when they might be hitting some kind
of bug.
