I try to revoke certificate from code I got exception with info about nonce.

public void revokeAndApprove(int certificateId) {

CertId certId = new CertId(certificateId);
long nonce = new Random().nextLong();
CertRevokeRequest revokeRequest = new CertRevokeRequest();
revokeRequest.setReason(RevocationReason.KEY_COMPROMISE);
revokeRequest.setComments("user request revoke");
revokeRequest.setNonce(nonce);

CertRequestInfo revokeInfo = certClient.revokeCert(certId, revokeRequest);// here comes an exception

CertReviewResponse reviewData = certClient.reviewRequest(revokeInfo.getRequestId());
reviewData.setNonce(""+nonce);
log(reviewData.toString());
reviewData.setRequestNotes("revoke approved");
certClient.approveRequest(reviewData.getRequestId(), reviewData);
}

when I use this I get exception on line(certClient.revokeCert(...))

and few other options I'v tried

1. Long nonce = transportCert.getNonce(); // null

2. Long nonce = certClient.getCert(certId).getNonce() //also a null

puting null to setNonce, or not setting it at all give me:

I check browser form from enduser entity and nonce value looks like this:"certId:someLongRandomNumber"

Am I not understanding usage of nonce or something in my code is wrong?
