RFC 7797 JWS Unencoded Payload doesn't work.

I need to generate jws with an unencoded payload according to RFC 7797.

I’ve written code according to your wiki tutorial:

public static String createJwsSignature() throws CertificateException, UnrecoverableEntryException, NoSuchAlgorithmException, KeyStoreException, IOException, JoseException {
    JsonWebSignature signerJws = new JsonWebSignature();
    signerJws.setPayload("{\"key\": \"value\"}");

    signerJws.getHeaders().setObjectHeaderValue(HeaderParameterNames.BASE64URL_ENCODE_PAYLOAD, false);

    signerJws.setCriticalHeaderNames(
            HeaderParameterNames.BASE64URL_ENCODE_PAYLOAD
    );
    signerJws.setKeyIdHeaderValue("213081410402036757863450612430055725658");
    signerJws.setAlgorithmHeaderValue("RS256");

    signerJws.setKey(HttpClientUtil.getPrivateKey());

   return signerJws.getCompactSerialization();
}

And it generates me a jws with an encoded payload :

When I call signerJws.toString() It get me correct header structure but anyway payload is encoded in the final jws.

JsonWebSignature{"b64":false,"crit":["b64"],"kid":"213081410402036757863450612430055725658","alg":"RS256"}
