API-интерфейс Bitmex с использованием API-интерфейса JAVA Ошибка SSLHandShakeException

Question

Я использую этот разъем API для подключения к Bitmex:

https://github.com/BitMEX/api-connectors/tree/master/auto-generated/java

Я использую Eclipse для моей программы JAVA и вручную установил JARS в соответствии с инструкциями:

target/swagger-java-client-1.0.0.jar

а также

target/lib/*.jar 

Тем не менее, когда я пытаюсь запустить следующий код:

import io.swagger.client.*;
import io.swagger.client.auth.*;
import io.swagger.client.model.*;
import io.swagger.client.api.AnnouncementApi;

import java.io.File;
import java.util.*;

public class TradingBot {

   public static void main(String[] args) {
    AnnouncementApi apiInstance = new AnnouncementApi();
        String columns = "columns_example";
        try {
            List<Announcement> result = apiInstance.announcementGet(columns);
            System.out.println(result);
        } catch (ApiException e) {
            System.err.println("Exception when calling AnnouncementApi#announcementGet");
            e.printStackTrace();
        }

    }

}

У меня эта ошибка:

Интересно, пытался ли кто-нибудь реализовать Java ApiConnector от Bitmex по ссылке выше и столкнулся с той же ошибкой? Если так, как это было решено? Я застрял в этом в течение некоторого времени. Любая помощь будет оценена! Заранее спасибо!
