Error while converting a JSON String to JSONObject in java using json.simple. Runtime Exception occurs

Question

My String result = {"userName":"balaji@tispl.in","authenticationResult":true,"errorMessage":"No errors."}

I want to Parse this String using json.simple & convert into a json object.
My code is as below:

package in.tispl.phoenix8;
    
    import org.json.JSONException;
    import org.json.JSONObject;
    import org.json.simple.parser.JSONParser;
    import org.json.simple.parser.ParseException;
    
    import java.io.FileNotFoundException;
    import java.io.FileReader;
    import java.io.IOException;
    
    public class Client {
        
        public static void main(String[] args) {
            HttpReq httpr = new HttpReq();
            httpr.setRequrl("http://www.crogress.com:8080/crogress/authenticateUser?userName=balaji@tispl.in&password=xxxxx");
            String result = httpr.getrequest();
            System.out.println(result);
            JSONObject jsonObject = createJSONObject(result);
            System.out.println(jsonObject);
        }
    
        private static JSONObject createJSONObject(String jsonString){
            JSONObject  jsonObject=new JSONObject();
            JSONParser jsonParser=new  JSONParser();
            if ((jsonString != null) && !(jsonString.isEmpty())) {
                try {
                    jsonObject=(JSONObject) jsonParser.parse(jsonString);
                } catch (org.json.simple.parser.ParseException e) {
                    e.printStackTrace();
                }
            }
            return jsonObject;
        }
    
    }

I am getting the below Error:
