> Class HttpServletResponseBufferingWrapper contains subtle bug when it comes to buffering of response. It relies its behaviour on HTTP status code and buffers only if it was set to 404.
> However, in following scenario current implementation won't work:
> 1. stream = response.getOutputStream() //non buffering output stream is returned because by default status code is set to 200
> 2. response.setStatusCode(404)
> 3. stream.write() //write details about error, this is going to be written to response because non-buffering output stream is in use
> 4. response.resetBufferedResponse() //this fails with IllegalStateException
