我在项目部署方面遇到问题。这是我得到的错误：

当我在代码中添加一个新函数时发生这种情况，我在其中调用另一个类的函数来生成安全证书。这是进行调用的函数的代码：
public static void generateCert(String name, KeyPair key, int days, String algorithm) throws GeneralSecurityException, IOException{
System.out.println("Starting to generate certificate");
X509Certificate cert = CertificationAuthority.generateCertificate(name, key, days, algorithm);
//return cert;
}
它确实进行了打印，但随后发生了错误。生成证书在另一个类（CertificationAuthority 类）中，代码如下：
public static X509Certificate generateCertificate(String dn, KeyPair pair, int days, String algorithm)
throws GeneralSecurityException, IOException
{
PrivateKey privkey = pair.getPrivate();
X509CertInfo info = new X509CertInfo();
//caso haja tempo, tratar isto com long + long
Date from = new Date();
Date to = new Date(from.getTime() + days * 864000001);
CertificateValidity interval = new CertificateValidity(from, to);
BigInteger sn = new BigInteger(64, new SecureRandom());
X500Name owner = new X500Name(dn);
info.set(X509CertInfo.VALIDITY, interval);
info.set(X509CertInfo.SERIAL_NUMBER, new CertificateSerialNumber(sn));
info.set(X509CertInfo.SUBJECT, new CertificateSubjectName(owner));
info.set(X509CertInfo.ISSUER, new CertificateIssuerName(owner));
info.set(X509CertInfo.KEY, new CertificateX509Key(pair.getPublic()));
info.set(X509CertInfo.VERSION, new CertificateVersion(CertificateVersion.V3));
AlgorithmId algo = new AlgorithmId(AlgorithmId.md5WithRSAEncryption_oid);
info.set(X509CertInfo.ALGORITHM_ID, new CertificateAlgorithmId(algo));
// Sign the cert to identify the algorithm that's used.
X509CertImpl cert = new X509CertImpl(info);
cert.sign(privkey, algorithm);
// Update the algorithm, and resign.
algo = (AlgorithmId)cert.get(X509CertImpl.SIG_ALG);
info.set(CertificateAlgorithmId.NAME + "." + CertificateAlgorithmId.ALGORITHM, algo);
cert = new X509CertImpl(info);
cert.sign(privkey, algorithm);
certificates.add(cert);
return cert;
}
我不明白为什么我会收到这个错误。我正在尝试测试 generateCertificate 方法的功能，但由于此错误，我无法做到这一点。
任何人都知道发生了什么？
