尝试初始化ApnsServiceBuilder时遇到异常

我需要一个.p12文件以便通过Apple的通知服务器进行身份验证，并且发现了一些问题。据我了解，我需要生成.csr和标识我的机器的私钥。因此，我需要在本地计算机上执行以下命令：

*$:~/Escritorio/curro/certificados$ openssl req -out CSR.csr -new -newkey rsa:2048 -nodes -keyout privateKey.key
Generating a 2048 bit RSA private key

将新的私钥写入“ privateKey.key”

现在，使用我的CSR.csr文件，需要登录到：

https://developer.apple.com/account/ios/certificate/certificateCreate.action?formID=62653259

然后提供之前生成的.csr文件，然后系统给我一个.cer文件（aps_development.cer）。现在，使用这个.cer文件，我必须生成它的.p12等价文件。为此，我需要从Apple生成的.cer文件中创建一个.pem文件。这是命令：

@Ubuntu:~/Escritorio/curro/certificados$ openssl pkcs12 -export -inkey privateKey.key -in developer_identity.pem -out iphone_dev.p12
Enter Export Password:
Verifying
Enter Export Password:

之后，我有了一个.p12文件，我需要初始化一个ApnsService实例，

@Component
public class NotificationServer implements Runnable, BeanFactoryAware {

@Autowired
// APNS channel
private ApnsService serviceApns;
private String apns_payload;

@PostConstruct
public void init() {
// build apns service path_to_apns_certificate, absolute path .p12 file 
String path_to_apns_certificate = config.getProperty("a-path");
//pass used to generate the .p12 file       
String password_apns_cert = config.getProperty("a-path");
log.debug("path_to_apns_certificate: " + path_to_apns_certificate);
//keep an eye with this!, this builder is non thread safe!
ApnsServiceBuilder apnsbuilder = new ApnsServiceBuilder();

String sMaxConections = config.getProperty("maxConections");
log.debug("sMaxConections: " + sMaxConections);
int maxConections = Integer.parseInt(sMaxConections);
apnsbuilder.asPool(maxConections );
String connectWithAppleApns = config.getProperty("apns.production");
log.debug("connectWithAppleApns: " + connectWithAppleApns);
apnsbuilder.withAppleDestination(new Boolean(connectWithAppleApns));
//here the exception is launched!       
apnsbuilder.withCert(path_to_apns_certificate, password_apns_cert);
serviceApns =apnsbuilder.build();       
}
}

这是错误消息：
