new Url(url)でデータを取得する際に、url の ssl 証明書の問題（期限切れなど）が原因でエラーが発生します。

まず、TrustManagerを実装します。

static class miTM implements javax.net.ssl.TrustManager, javax.net.ssl.X509TrustManager {
    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
        return null;
    }

    public boolean isServerTrusted(java.security.cert.X509Certificate[] certs) {
        return true;
    }

    public boolean isClientTrusted(java.security.cert.X509Certificate[] certs) {
        return true;
    }

    public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType)
            throws java.security.cert.CertificateException {
        return;
    }

    public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType)
            throws java.security.cert.CertificateException {
        return;
    }
}

デフォルトのクライアントを設定し、setDefaultHostnameVerifierをtrueに設定します。

javax.net.ssl.TrustManager[] trustAllCerts = new javax.net.ssl.TrustManager[] {new miTM()};
javax.net.ssl.SSLContext sc = javax.net.ssl.SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, null);
javax.net.ssl.HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
// 検証をスキップ
javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
    @Override
    public boolean verify(String hostname, SSLSession session) {
        return true;
    }
});
