Hey, guys! I’m still issued by that on Hibernate 5.4.10.Final. I’ve had an

interface HasId<T extends Serializable> {
  T getId();
}

and implementation

public class AbstractNumericId extends HasId<Long> {
  @Id
  private long id;
  
  @Override
  public Long getId() {
    return id;
  }
}

But when I load entity via session.load() and call to entity.getId(), it still makes a request to database

var entity = session.load(cls, id);
entity.getId(); // makes a request to DB

The workaround for this is to declare id like this

@Id
@Access(PROPERTY)
private long id;
