Buggy source:
private String getUserCookies(){
  Map<String,String> cookieMap=(Map)httpRequest.getAttribute("String_Node_Str");
  if (cookieMap == null || cookieMap.get("String_Node_Str") == null) {

Fixed version (ground truth):

    if (cookies != null) {
      for (      Cookie cookie : cookies) {
        cookieMap.put(cookie.getName(),cookie.getValue());
      }
    }
    if (!cookieMap.containsKey("String_Node_Str")) {
      try {
        String authHeader=httpRequest.getHeader("String_Node_Str");
