JcaX509CertificateHolder missed in bouncy castle 1.78.1

[a-bayat]

I have updated my bouncy castle from bcpkix-jdk15on to bcpkix-jdk18on and bcprov-jdk15on to bcprov-jdk18on both version is 1.78.1.
but now I have trouble with my code that I could not find JcaX509CertificateHolder! here is my code is there any suggestion to solve this:

private  static boolean checkIfValidBIC8(X509Certificate cert, String bic8Code) throws CertificateNotYetValidException, CertificateExpiredException, CertificateEncodingException {
        Boolean result = true;
        try {
            cert.checkValidity();
            PublicKey key = cert.getSubjectX500Principal();

            X500Name x500name = new JcaX509CertificateHolder(cert).getSubject();
            RDN orgId = x500name.getRDNs(BCStyle.O)[0];
            AttributeTypeAndValue orgAttr = orgId.getFirst();
            String extractedBIC8FromCertificateO = "";
            if (orgAttr.getValue() != null)
                extractedBIC8FromCertificateO = orgAttr.getValue().toString().trim().toUpperCase();


            if (!extractedBIC8FromCertificateO.contains(bic8Code.trim().toUpperCase())) {
                logger.error("the given bicCode8:["+bic8Code+"] is mismatched with the server certificate !");
                result = false;
            }
        }
        catch (Exception e) {
            result=false;
        }
        return result;
    }

It's definitely in there. I'd check the classpath again. Your update may not have gone entirely to plan.
