Description

The following code:

import test.CryptoUtils; // loads an RSA private key from file
import org.apache.cxf.rs.security.jose.jwk.JsonWebKey;
import org.apache.cxf.rs.security.jose.jwk.JsonWebKeys;
import org.apache.cxf.rs.security.jose.jwk.JwkUtils;

import java.io.FileOutputStream;
import java.io.IOException;
import java.nio.file.Paths;
import java.security.interfaces.RSAPrivateKey;
import java.time.LocalDateTime;

public class TestCase {

    public static void main(String[] args) throws IOException {
        final RSAPrivateKey privateKey = CryptoUtils.loadRsaPrivateKey(Paths.get("a-private-key.der"));
        final JsonWebKey jwk = JwkUtils.fromRSAPrivateKey(privateKey, "RSA-OAEP-256");
        jwk.setKeyId("test");
        jwk.setKeyProperty("created-at", LocalDateTime.now());

        final JsonWebKeys webKeys = new JsonWebKeys(jwk);

        JwkUtils.jwkSetToJson(webKeys, new FileOutputStream("test.jwk.json"));
    }

}

Produces the following malformed JSON:

{
  "keys": [
    {
      "kty": "RSA",
      "alg": "RSA-OAEP-256",
      "n": "...",
      "d": "...",
      "p": "...",
      "q": "...",
      "dp": "...",
      "dq": "...",
      "qi": "...",
      "kid": "test",
      "created-at": 2016
      -0
      8
      -10
      T11: 0
      1: 51.036
    }
  ]
}

Basically the `LocalDateTime` is not converted to `String` before getting serialized to JSON.
