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

Hi Rossen.

I think you did find a bug in Pluto after all :)
As you correctly pointed out, the MimeResponse.getPortletOutputStream only returns a java.io.OutputStream which the Pluto 
HttpServletResponseWrapper simply *assumes* to be upcastable to ServletOutputStream (which it is by default).
As Portlets are allowed to wrap/filter the response however, this assumption cannot be safely made.
I created a new issue for this: https://issues.apache.org/jira/browse/PLUTO-591
This will be fixed with the next 2.0.2 release of Pluto which is planned within the next few weeks.

Thanks for reporting this!

Regards,

Ate
