@JsonbTypeDeserializer and @JsonbTypeSerializer don't work in the fields

Question

I'm in an activity of exchanging Jackson for Jsob-B and I am having a problem on use @JsonbTypeDeserializer and @JsonbTypeSerializer as told below.

I have an entity like this:

 public class User implements Serializable {

  private static final long serialVersionUID = 1L;

  private String login;

  @JsonbTypeDeserializer(Decrypting.class)
  @JsonbTypeSerializer(Encrypting.class)
  private String password;

  // getters and setter
}

And one test like this:

  @Test
  public void whenDeserializingUsingJsonbTypeDeserializer() throws IOException {

    String json = "{\"login\":\"admin\", \"password\":\"yfv_ntl3_Nbrv0139tDwRQ\"}";

    Jsonb jsonb = JsonbBuilder.create();

    User user = jsonb.fromJson(json, User.class);

    Assert.assertEquals(user.getPassword(), "test-string");
  }

When running the test, the Decryption class is trying to deserialize the login field, but, as you can see, only the password field has annotations.

Any way to fix it?

`the deserializer is trying to deserialize the login field` sounds logic... you mean that it use your custom deserializer for login too ? — CodeScale, Apr 29 '20 at 08:22
What I meant is that I don't want the Decrypting class to be used to deserialize the login field, this is what is happening. — Luciano Borges, Apr 29 '20 at 08:27

After update for new versions, I had a problem with JsonbConfigProperties.FAIL_ON_UNKNOWN_PROPERTIES that I switched for YassonConfig.FAIL_ON_UNKNOWN_PROPERTIES and now everything works fine.
