Ошибка загрузки p12 в WAS Liberty на bluemix: java.io.IOException: недостаточно данных

Я пытаюсь загрузить p12 для отправки уведомлений APNS с помощью:

InputStream in = new FileInputStream(certPath);
KeyStore ks = KeyStore.getInstance("PKCS12");
ks.load(in, certPass.toCharArray());

Ошибка при выполнении в среде выполнения bluemix Liberty с IBM jdk.
