Infinite loop for @OneToOne @Entity in BasicPersistentEntity.doWithAssociations()? [DATAREST-778]

member sound opened DATAREST-778 and commented

The following bean structure causes an infinite loop when using @RepositoryRestResource.
The important part is the @OneToOne mapping with a "circular" reference. Even though I annotated it with RestResource @JsonIgnore, the infinite loop is still caused:

@RepositoryRestResource(PersonProjection.class)
interface PersonRepository extends PagingAndSortingRepository<Person, Long> (){

}

@Entity
public class Person {
    @Id
    private long id;
    private String name;

    //assuming each car can be linked to one person only
    @OneToOne(mappedBy = "person", cascade = CascadeType.ALL, orphanRemoval = true)
    private Car car;
}

@Entity
public class Car {
	@Id
	private Long id;
	private String name;

	@OneToOne
	@JoinColumn(name = "fk_person_id", foreignKey = @ForeignKey(name = "fk_person"))
	@RestResource(exported = false)
	@JsonIgnore
	private Person person;
}

@Projection(name = "personProjection", types = Person.class)
public interfaace PersonProjection {
    String name();
}

Result:
