receiving rsa_fixed_dh or dss_fixed_dh cert request types causes null pointer.

Pierre of HP reports that SSL-C is throwing NullPointerExceptions:

The problem is with the code here. If we receive anything
besides DSA and RSA, we are sending a null keytype into the KM:
 
                String keyType = null;

                if (certRequest.types[i] == CertificateRequest.cct_rsa_sign)
                    keyType = "RSA";
                else if (certRequest.types[i] ==
                        CertificateRequest.cct_dss_sign)
                    keyType = "DSA";
                alias = km.chooseClientAlias(new String[] { keyType },
                        certRequest.getAuthorities(), conn);
