StackOverflowError when requesting Json Schema for profile when entity contains member of same type [DATAREST-1282]

Tony Harrison opened DATAREST-1282 and commented

When and entity contains a member variable of the same type/class requesting the json-schema of the profile results in StackOverflowError

eg:

@Value
@Builder
public class Item {
    private String name;
    private Item child;
}

@RepositoryRestResource
public interface ItemRestRepository extends Repository<Item, String>, QueryByExampleExecutor<Item> {
    Page<Item> findAll(Pageable var1);
    Optional<Item> findById(String var1);
}

curl -H "Accept: application/schema+json" http://localhost:8080/profile/items
