Join Annotation Does Not Change MongoDB Query

[SenorPez]

Expected Behavior

By default, a find query should be generated by the repository interface. According to the documentation (https://micronaut-projects.github.io/micronaut-data/latest/guide/#mongoJoinQueries), using the Join annotation switches to the aggregation pipeline to populate relationship fields.

Actual Behaviour

It doesn't.

@MongoRepository
public interface StarSystemRepository extends CrudRepository<StarSystem, Integer> {
}

and

@MongoRepository
public interface StarSystemRepository extends CrudRepository<StarSystem, Integer> {
    @Override
    @Join("stars")
    @NonNull List<StarSystem> findAll();
}

generates an identical find query.

{"find": "starSystems", "filter": {"_id": {"$eq": 867158537}}, "limit": 1, "singleBatch": true, "$db": "pezdb", "lsid": {"id": {"$binary": {"base64": "qKkxNgeFTdi4SwSSwNvnHA==", "subType": "04"}}}}

The aggregation pipeline is never called, so objects are never populated. Placing the Join annotation in other places (under the Relationship, creating a non-Override interface method, etc.) also never stop the generation of that same find query. The related object is never populated.
