NullPointerException During executeCommand

I'm getting the following error while executing a simple command with executeCommand:

Source code:

  1 package com.citadel.bootcamp;

  3 import io.cloudsoft.winrm4j.client.WinRmClientContext;
  4 import io.cloudsoft.winrm4j.winrm.WinRmTool;
  5 import io.cloudsoft.winrm4j.winrm.WinRmToolResponse;
  6 import org.apache.http.client.config.AuthSchemes;

  8 public class HelloMSW {
  9   public static void main(String[] args) {
 10     WinRmClientContext context = WinRmClientContext.newInstance();
 11
 12     WinRmTool tool = WinRmTool.Builder.builder("wd-qts-gidb197", "", "")
 13         .authenticationScheme(AuthSchemes.KERBEROS)
 14         .port(5985)
 15         .useHttps(false)
 16         .disableCertificateChecks(true)
 17         .context(context)
 18         .build();
 19
 20     if (tool == null) {
 21         System.out.println("Failed to build WinRM tool\n");
 22     } else {
 23         WinRmToolResponse resp = tool.executeCommand("echo hi");
 24     }
 25
 26
 27     context.shutdown();
 28   }
 29 }
