HttpServletPortletResponseWrapper incorrectly assumes
MimeResponse.getPortletOutputStream() is upcastable to ServletOutputStream

Project: Pluto
Issue Type: Bug
Components: portlet container
Affects Versions: 2.0.0
Reporter: Ate Douma

Hi, I am attempting to use Sun's jsf-portlet integration with Pluto 2.0. I get
the following:
Caused by: java.lang.ClassCastException:
com.sun.faces.portlet.ByteArrayWebOutputStream cannot be cast to
javax.servlet.ServletOutputStream

The JavaDocs for javax.portlet.MimeResponse indicates the
getPortletOutputStream() method return value is of type java.io.OutputStream.
Hence the cast to javax.servlet.ServletOutputStream in
HttpServletPortletResponseWrapper seems dodgy. Can you confirm if this is
indeed an issue with Pluto's implementation or not?
Thanks,
Rossen
