> In ClientHandler.responseReceived(), if the resposne.getStatusLine().getStatusCode() is HttpStatus.SC_BAD_REQUEST, we log the error and return.  After this, IO Reactor tries to stream the response content to us with a call to inputReady(), however the RESPONSE_SINK_BUFFER will be null, so we throw a NullPointerException.  IO Reactor will continue to try to deliver content to us, so the result is a huge pile of NullPointerExceptions.
> Easy fix seems to be to call "processResponse()" in the SC_BAD_REQUEST case of the switch statement, like every other case does.
