PUSHY не удалось отправить push-уведомление от Apple на tomcat 7

Question

Я использую PUSHY (0.13.3) со всеми зависимостями от tomcat 7 для отправки кода push-уведомлений:

SimpleApnsPushNotification pushNotification = new SimpleApnsPushNotification(token, "com.xxxx.app", payload);

apnsClient = new ApnsClientBuilder()
                    .setApnsServer(bpushProd ? ApnsClientBuilder.PRODUCTION_APNS_HOST:ApnsClientBuilder.DEVELOPMENT_APNS_HOST, ApnsClientBuilder.ALTERNATE_APNS_PORT)
                    .setSigningKey(ApnsSigningKey.loadFromPkcs8File(new File(pathToP8File),
                            "TEAMID", "KEYID"))
                    .build();

final PushNotificationFuture<SimpleApnsPushNotification, PushNotificationResponse<SimpleApnsPushNotification>>
                    sendNotificationFuture = apnsClient.sendNotification(pushNotification);

try {
final PushNotificationResponse<SimpleApnsPushNotification> pushNotificationResponse = sendNotificationFuture.get();

if (pushNotificationResponse.isAccepted()) {
    System.out.println(" ^^^ Push notification accepted by APNs gateway.");
} else {
        System.out.println("**** Notification rejected by the APNs gateway: " +
                                    pushNotificationResponse.getRejectionReason() + "\n****"+ pushNotificationResponse.toString());

if (pushNotificationResponse.getTokenInvalidationTimestamp() != null) {
    System.out.println("\t…and the token is invalid as of " + pushNotificationResponse.getTokenInvalidationTimestamp());
 }
}
} catch (final ExecutionException e) {
    System.err.println("Failed to send push notification.");
                        e.printStackTrace();
                    }

но получил исключение
