То, как проигнорировать здание пути PKIX, перестало работать: sun.security.provider.certpath. SunCertPathBuilderException?

Я получил следующее исключение когда попытка отправить запрос на http сервер:

Вот код, который я использовал

URL url = new URL(
        "https://www.abc.com");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();

conn.setRequestMethod("GET");

conn.setDoOutput(true);

DataOutputStream wr = new DataOutputStream(conn.getOutputStream());
// wr.writeBytes(params);
wr.flush();
wr.close();

BufferedReader br = new BufferedReader(new InputStreamReader(
        conn.getInputStream()));
String line = null;
while ((line = br.readLine()) != null) {
    System.out.println(line);
}

Вот исключение:

Сервер не принадлежит мне. Существует ли способ проигнорировать это исключение?
