                    request.param(requestEntry.getKey() != null ? requestEntry.getKey().toString() : null,requestEntry.getValue() != null ? requestEntry.getValue().toString() : null);
                }
            }
            ContentResponse response = request.send();
            resultString = StringUtilities.toStringCleanBom(response.getContent());
        } catch (Exception e) {
            throw new BaseException("Error in http client request", e);
        } finally {
            try {
                httpClient.stop();
            } catch (Exception e) {
                logger.error("Error stopping http client", e);
            }
        }
        return resultString;
    }

what result do you expect? What is the error message actually seen?

request.param(requestEntry.getKey() != null ? requestEntry.getKey().toString() : null,requestEntry.getValue() != null ? requestEntry.getValue().toString() : null);

I think there is no problem after checking it again and again with the context. Please take a look at it
