当我的服务器尝试根据设备令牌和ck.pem（.pem文件，证书和密钥之间的组合）将通知推送到特定设备时，我遇到了此错误。

Caused by: java.io.IOException: toDerInputStream rejects tag type 45

这是完整的错误信息出现在我的eclipse控制台。

我怀疑这个错误是由这个代码引起的

System.out.println("reg id =" + record.getRegId());
ApnsService service = APNS.newService().withCert("/Applications/MAMP/htdocs/xxxxx-mobile/ck.pem", "xxxxxx").withSandboxDestination().build();
String payload = APNS.newPayload().alertBody("This for testing").build();
String token = record.getRegId();
service.push(token, payload);

你对这个toDerInputStream rejects tag type 45有什么想法吗？
我已经在这里做了关于这个问题的研究：

2. Java APNS (Apple Push Notification Service) error
   为什么？
