title: Lombok builder pattern with jackson JsonProperty
body: <p>I have constructed a Java Object using lombok with builder pattern. But, I am getting the following exception when trying to deserialize a Java object using  Jackson. This occurs for fields which has <code>@JsonProperty</code> annotation. </p>
  
  <blockquote>
    <p>Exception in thread "main" com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "user_name" (class User$UserBuilder), not marked as ignorable (2 known properties: "userName", "userId"])<BR>
     at [Source: (String)"{"userId":1,"user_name":"username"}"; line: 1, column: 26] (through reference chain: User$UserBuilder["user_name"])</p>
  </blockquote>
  
  <p>Code Used : </p>
  
  <pre><code>public class TestJson {
      public static void main(String args[]) throws Exception {
          ObjectMapper objectMapper = new ObjectMapper();
  
          User user = User.builder()
                  .userName("username")
                  .userId(1)
                  .build();
          System.out.println(user);
          String string = objectMapper.writeValueAsString(user);
          System.out.println(string);
          user = objectMapper.readValue(string, User.class);
          System.out.println(user);
      }
  }
  
  
  @JsonDeserialize(builder = User.UserBuilder.class)
  @Getter
  @ToString
  @Builder(toBuilder = true)
  class User {
      @JsonProperty("user_name")
      @NonNull
      private String userName;
  
      @JsonProperty
      private int userId;
  
      @JsonPOJOBuilder(withPrefix = "")
      public static class UserBuilder {
  
      }
