[jcifs] NTLM - getOutputStream() has already been called for this response

[Bill Comer]

Using spring-security 2.0.4 and spring 2.5.5, with jcifs 1.2.25

Trying to download a file gets the stacktraces shown below.
I have found this jcifs post dating wayback to 2004
http://markmail.org/message/xrpgja4jvcglhguh#query:related%3Axrpgja4jvcglhguh+page:1+mid:xrpgja4jvcglhguh+state:results
but the proposed solution does not appear to have been implemented.

I believe the problem is related to the IE Post problem I raised
recently but the fix for that described
http://billcomer.blogspot.com/2009/01/ntlm-authentication-and-ie-post-problem.html
does not fix this issue.

On the screen the follwoing stacktrace is shown:
   org.apache.jasper.JasperException: java.lang.IllegalStateException:
getOutputStream() has already been called for this response
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:522)

Furhter up the console there is:

The call in the controller causing all the problems is  url.openStream():

                                  HttpServletResponse response,
                                  Object command,
                                  BindException errors)
    throws Exception
    {
      File file = getFile();
      String fileURL = "http://" + request.getServerName() + ":"
          + request.getServerPort() + request.getContextPath() + "/"
          + findPrintDir(file) + "/" + file.getName();
      URL url = new URL(fileURL);
      url.openStream();
      ......
   }

Ant thoughts please?
