MarshallingView should not close response output stream [SPR-11411]

[spring-projects-issues]

Roberto Franchini opened SPR-11411 and commented

The method renderMergedOutputModel should not close the HttpServletResponse output stream.
The called utility method
FileCopyUtils.copy(bos.toByteArray(), response.getOutputStream());
closes the stream avoiding other output filters adding more informations.

Use streamUtils instead

For example, if the view is invoked by a url under security, the session id cookie isn't sent back to the client.
