Please review this fix to improve the error handling for attempts to store a Certificate object in PKCS12 keystore. The PKCS12 keystore implementation supports storing only X509Certificate objects but the KeyStore API allows Certificate objects. This fix rejects attempts to store non-X.509 certificates and throws a KeyStoreException.
