Buffering of response does not work correctly in SSF

                 Key: COCOON-2237
             Project: Cocoon
          Issue Type: Bug
          Components: - Servlet service framework
    Affects Versions: 2.2
            Reporter: Grzegorz Kossakowski
            Assignee: Grzegorz Kossakowski
             Fix For: 2.2

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
