With the entity below, we have the warning with a batch of 52 {{EntityCC}}in the insertion list (only these 52 objects in the list), with a unique parent{{EntityCC}}object in the update list (alone in the update list)…

public class EntityCC {
	
	@Id
	private Long id;
	
	@ManyToOne(fetch = FetchType.LAZY)
	@JoinColumn(name = "entity_cc_parent_id")
	private EntityCC parent;
}

So not sure the warning is relevent here…
