      Hi, since this commit https://github.com/resteasy/Resteasy/commit/d046c8ded640a952ae48a36fd3f09c456bd9ca4d

      class: ResteasyJackson2Provider

      mapper.setPolymorphicTypeValidator(new WhiteListPolymorphicTypeValidatorBuilder().build());

      It erases the existing PolymorphicTypeValidator.

      For example, I'm using the following custom ObjectMapper that defines a `PolymorphicTypeValidator` where I allow User.class.
      But ResteasyJackson2Provider erases my settings.

      @Provider
@Produces(MediaType.APPLICATION_JSON)
public class JacksonConfig implements ContextResolver<ObjectMapper> {
  private final ObjectMapper objectMapper;

  public JacksonConfig() {
    objectMapper = new SafeObjectMapper();
    objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
    objectMapper.setPolymorphicTypeValidator(new WhiteListPolymorphicTypeValidatorBuilder().allowIfBaseType(User.class).build());
  }

  @Override
  public ObjectMapper getContext(Class<?> type) {
    return objectMapper;
  }
}

      I endup with the following stacktrace:

      javax.ws.rs.client.ResponseProcessingException: javax.ws.rs.ProcessingException: com.fasterxml.jackson.databind.exc.InvalidTypeIdException: Could not resolve type id 'com.learnkeeper.shared.entities.OAuth2User' as a subtype of `com.learnkeeper.shared.entities.OAuth2User`: Configured `PolymorphicTypeValidator` (of type `com.fasterxml.jackson.databind.jsontype.BasicPolymorphicTypeValidator`) denied resolution

      An approach to fix it, could be to check if mapper.getPolymorphicTypeValidator() == null:

          if (endpoint == null) {
      ObjectMapper mapper = locateMapper(type, mediaType);
      if (mapper.getPolymorphicTypeValidator() == null) {
        mapper.setPolymorphicTypeValidator(new WhiteListPolymorphicTypeValidatorBuilder().build());
      }
      endpoint = _configForReading(mapper, annotations, null);
      _readers.put(key, endpoint);
    }
