Fixed version (ground truth):
private void prepareJsVariables(ResponseEntity<String> httpResponse){
  this.responseCode=new NativeObject();
  if (httpResponse != null) {
    Map<String,String> headers=httpResponse.getHeaders().toSingleValueMap();
    List<Object> headerList=new ArrayList<Object>(headers.size());
    for (    Map.Entry h : headers.entrySet()) {
      NativeObject hobj=new NativeObject();
      hobj.put("String_Node_Str",hobj,h.getKey());
      hobj.put("String_Node_Str",hobj,h.getValue());
      headerList.add(hobj);
    }
    this.responseHeaders=new NativeArray(headerList.toArray());
    this.responseBody=Context.javaToJS(httpResponse.getBody(),scope);
    this.responseCode.put("String_Node_Str",responseCode,httpResponse.getStatusCode().value());
    this.responseCode.put("String_Node_Str",responseCode,httpResponse.getStatusCode().name());
    this.responseCode.put("String_Node_Str",responseCode,httpResponse.getStatusCode().toString());
  }
