You're right.  I see that under the JSP spec description for the include directive:

The workaround seems to be to have the base jsp file create the cookies.
But doing that also seems to fail.  Flipping around the example files I used above, the following also fails to create the cookie.  Just including the file seemed to cause it to fail to create the cookie. 

          jsptest.jsp
<%@ page contentType="text/html" %>
  | 
  | <jsp:include page="./cookietest.jsp" flush="true"/>
  | 
  | <jsp:directive.page import="javax.servlet.http.Cookie"/>
  | <jsp:scriptlet><![CDATA[
  |    Cookie c = new Cookie("NewCookie","Data for Cooki");
  |    out.println(c.getName()+": "+c.getValue()+"<br/>");
  |    response.addCookie(c);
  | ]]></jsp:scriptlet>
  | 
  | <html><body>
  | <center><b>JSP Test</b></center>
  | </body></html>

          cookietest.jsp
<%@ page contentType="text/html" %>
  | <html><body>
  | <p>
  | Hello from included page.
  | </p>
  | </body></html>

After commenting out the include, the cookies show up.
Is this what I should expect?  Is there something else that I need to do?

<!-- jsp:include page="./cookietest.jsp" flush="true"/ -->
