MongoDB Panache ObjectId in native image mode

[szabolcs-dekany]

Hey all! I'm currently having in issue with running my simple little app in native image mode.

I have the following simple entity:

@Builder // Lombok
@MongoEntity(collection = "entity")
public class SomeEntity extends PanacheMongoEntity {
  public LocalDate createdAt;
}

I have to simple transactional method that creates an entity of this type:

@Transactional
  public String createEntity() {

    var entity = SomeEntity.builder()
        .createdAt(LocalDateTime.now(ZoneId.of("UTC"));)
        .build();
    entity.persist();
    return entity.id.toString();
  }

This setup works fine in regular JVM mode, an ObjectId is created automatically for the entity, but as soon as I compile it into a native image, this seem to not work and I'm getting NPs when trying to call return entity.id.toString();

Tried to see if its Lombok, tried it without the builder but it seemingly makes no difference. Anyone ran into this before?

Cheers,
Szabolcs

This is strange, it seems your Entity is not included in the native image but we register all of them.
Can you create a reproducer and open an issue ?
