I migrated hibernate *5.6.14.Final* to *6.1.7.Final* and I noticed a problem with entityGraph when exists query with explicit join fetch.
For example:
{noformat} @Query("select c from Company c join fetch c.factory f join fetch f.carFactory cf where c.id = :id")
Optional<Company> findByIdExplicitFetchFactoryAndCarFactory(long id);
@Query("select c from Company c where c in :company")
@EntityGraph(attributePaths = {"factory.carFactory.cars"})
Optional<Company> findByCompanyFetchCars(Company company);{noformat}
And this method does not fetch _cars_:
{noformat} @Transactional(readOnly = true)
public Company getTwoQueries(long id) {
return repository. findById findByIdExplicitFetchFactoryAndCarFactory (id)
.flatMap(repository:: findByIdExplicitFetchFactoryAndCarFactory findByCompanyFetchCars )
.orElseThrow(EntityNotFoundException::new);
}{noformat}
