Just another reason to why you shouldn't use Lombok, in another saying another reason to why you should write unit tests: You have two fields in your class. Fields are in the same type. You use @AllArgsConstructor to auto-generate your all args constructor. It works for a moment, until you change the order of the field.
import lombok.AllArgsConstructor;
import lombok.Data;
@Data
@AllArgsConstructor
public class LazyDeveloper {
private String firstName;
private String lastName;
