I am trying to send iOS push notifications using the Pushy Java library. The code to send the APNS looks like this:
String topic = "XXX";
ApnsClient apnsClient = new ApnsClientBuilder().setApnsServer(ApnsClientBuilder.DEVELOPMENT_APNS_HOST)
.setClientCredentials(new File(
"apns_a5400831-a2db-480b-9487-52cfe61fc4f0.p12"),
"Password123!")
.build();
ApnsPayloadBuilder payloadBuilder = new SimpleApnsPayloadBuilder();
String payload = payloadBuilder.buildMdmPayload(magic);
String sanitizedToken = TokenUtil.sanitizeTokenString(deviceToken);
try {
SimpleApnsPushNotification pushNotification = new SimpleApnsPushNotification(sanitizedToken, topic,
payload);
PushNotificationResponse<SimpleApnsPushNotification> pushNotificationResponse = apnsClient
.sendNotification(pushNotification).get();
if (pushNotificationResponse.isAccepted()) {
if (logger.isDebugEnabled()) {
logger.debug("testCheckin(String, String) - {}", "Push notification accepted by APNs gateway."); //$NON-NLS-1$ //$NON-NLS-2$
}
} else {
if (logger.isDebugEnabled()) {
logger.debug("testCheckin(String, String) - {}", //$NON-NLS-1$
"Notification rejected by the APNs gateway: " //$NON-NLS-1$
+ pushNotificationResponse.getRejectionReason());
}
pushNotificationResponse.getTokenInvalidationTimestamp().ifPresent(timestamp -> {
System.out.println("\t…and the token is invalid as of " + timestamp);
});
}
} catch (Exception e) {
logger.warn("testCheckin(String, String) - exception ignored", e); //$NON-NLS-1$
}
Much of this is taken straight from the documentation. When I run the code, though, I get the following Exception:

Am I doing something wrong here? Is there a different Java APNS library I should be using?
