ClassCastException using Sun's jsf-portlet.jar in Pluto 2.0

Hi, I am attempting to use Sun's jsf-portlet integration with Pluto 2.0. I
get the following:

Caused by: java.lang.ClassCastException:

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 an
issue with Pluto's implementation that needs to be raised?

Thanks,
Rossen
