Lazy Loading with Spring Data and HIbernate JPA

I am performing some tests with SpringData and Hibernate and found some interesting behavior on lazy loading and findBy... methods.

I have the following method on a child class.

List findByArtistCredit(Long artistCreditId);

and the following mapping between Recording and ArtistCredit...

@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="artist_credit" , referencedColumnName="artist_credit_id")
private ArtistCredit artistCreditReference; 

on the "One" side...

@OneToMany(fetch=FetchType.LAZY,mappedBy="artistCreditReference")
private Set<Recording> recordings; 

And what happens is that the collection on the "Many side" is being eagerly fetched...

Does anyone know "why is happening?"

Any answer is wellcome.

Regards.
