Apache POI цифровая подпись

Пытаюсь подписать word документ с помощью цифровой подписи используя Apache POI. Есть JKS хранилище с парой открытый-закрытый ключ. Вытаскиваю ключ из хранилища и пытаюсь подписать с помощью следующего кода:

public void sign() throws Exception {
  char password[] = "qwe".toCharArray();
  File file = new File("C:/testkeystore.pfx");
  KeyStore keystore = KeyStore.getInstance("JKS");
  FileInputStream fis = new FileInputStream(file);
  keystore.load(fis, password);
  fis.close();
  String alias = "pupkinv"; 
  Key key = keystore.getKey(alias, password);
  X509Certificate x509 = (X509Certificate)keystore.getCertificate(alias);
  SignatureConfig signatureConfig = new SignatureConfig();
  signatureConfig.setKey((PrivateKey)key);
  signatureConfig.setExecutionTime(cal.getTime());
  signatureConfig.setDigestAlgo(HashAlgorithm.sha256);

  signatureConfig.addSignatureFacet(new EnvelopedSignatureFacet());
  signatureConfig.addSignatureFacet(new KeyInfoSignatureFacet());
  signatureConfig.setSigningCertificateChain(Collections.singletonList(x509));
  OPCPackage pkg = OPCPackage.open("C:/123.docx", PackageAccess.READ_WRITE);
  signatureConfig.setOpcPackage(pkg);
  SignatureInfo si = new SignatureInfo();
  si.setSignatureConfig(signatureConfig);
  si.confirmSignature();

  for (SignaturePart sp : si.getSignatureParts()) {
    assert sp.validate();
  }
  assert si.verifySignature();
  pkg.close();
}

Выдает ошибку:

По трасирровке останавливается на si.confirmSignature(); Что я делают не так?
