Yes, there is a bug in Tomcat 3.1 (and possibly other servlet engines). To send a cookie through a redirect, you must set the headers manually. seanm@narus.com suggests:
Cookie long_term = new Cookie(LONG_TERM_COOKIE_NAME, user_name);
long_term.setMaxAge(60*60*24*4);
long_term.setPath("/Blah");
response.addCookie(long_term);

response.setStatus(HttpServletResponse.SC_MOVED_TEMPORARILY);
response.setHeader("Location",REDIRECT_PAGE);
