How to resolve error "java.lang.IllegalArgumentException: URI can't be null" when testing HTTP Event Collector from a Java client?

[SGADE]

I am trying to test the HTTP Event Collector from a java client, referred the Java project from splunk.com. Please help to resolve the issue.
We use cookie for the authorization . Thanks SG

        serviceArgs.setHost("https://test2751.md4.abc.com");
        serviceArgs.setCookie("credential=cookie value");
        serviceArgs.setPort(8088);
        serviceArgs.setScheme("https");
        serviceArgs.setToken("0B999603-81C7-4930-abcd-639825CE66E6");
        serviceArgs.setSSLSecurityProtocol(SSLSecurityProtocol.TLSv1_2); // TLSv1 didn't work.

      service = Service.connect(serviceArgs);
      service.login();

Below is the exception trace:

I was able to work-around these issues by effectively embedding the REST API with CURL into Java like this:

public String curlConnect() throws Exception {
        String r = null;
        try {
            List<String> theCommand = new ArrayList<String>();
            theCommand.add("curl");
            theCommand.add("-sk");
            theCommand.add(this.surl + "/services/auth/login?output_mode=json");
            logger.debug(this.surl+ "/services/auth/login?output_mode=json");
            logger.debug("-d username=" + this.user + " password=XXXXXX");
            theCommand.add("-d");
            theCommand.add("username=" + this.user);
            theCommand.add("-d");
            theCommand.add("password=" + this.token);

            ProcessBuilder pb = new ProcessBuilder(theCommand);

            pb.directory(new File(System.getProperty("input.file.path")));
            pb.redirectErrorStream(true);
            Process p = pb.start();
            InputStream is = p.getInputStream();

            r = IOUtils.toString(is);
            r = r.substring(r.indexOf("{\"sessionKey\":\""), r.length());
            JSONObject jsonResponse = new JSONObject(r);
            this.sessionKey = jsonResponse.getString("sessionKey");
            r = this.sessionKey;
            logger.debug(r);

        } catch ( Exception e ) {
            logger.error(this.surl);
            logger.error(e.getMessage());
            throw e;
        }
        return r;
    }

    public String query(String splunkQuery) throws Exception {
        String r = null;
        try {
            List<String> theCommand = new ArrayList<String>();
            theCommand.add("curl");
            theCommand.add("-sku");
            theCommand.add(this.user+":"+this.token);
            //theCommand.add("-H");
            //theCommand.add("\"Authorization: Splunk " + this.sessionKey + "\"");
            theCommand.add(this.surl + "/services/search/jobs?output_mode=json");
            logger.debug(this.surl+ "/services/search/jobs?output_mode=json");
            theCommand.add("-d");
            theCommand.add("search=" + URLEncoder.encode(splunkQuery, "UTF-8"));
            logger.info("search=" + URLEncoder.encode(splunkQuery, "UTF-8"));
            //theCommand.add("-d");
            //theCommand.add("output_mode=json");

            ProcessBuilder pb = new ProcessBuilder(theCommand);

            pb.directory(new File(System.getProperty("input.file.path")));
            pb.redirectErrorStream(true);
            Process p = pb.start();
            InputStream is = p.getInputStream();

            String theResult = IOUtils.toString(is);
            logger.info(theResult);

            theResult = theResult.substring(theResult.indexOf("{\"sid\":\""), theResult.length());
            JSONObject jsonResponse = new JSONObject(theResult);
            r = jsonResponse.getString("sid");

            while ( !resultsReady(r)) {
                logger.info("waiting 30 seconds for async report to finish running sid " + r);
                java.util.concurrent.TimeUnit.SECONDS.sleep(30);
            }
        } catch ( Exception e) {
            logger.error(this.surl);
            logger.error(e.getMessage());
            throw e;
        }
        return r;
    }

Bit ridiculous that following the provided example does not work isn't it?

Did you resolve this? I am having the same problem...
