Before hibernate 6 we had mapped fields like this(or without insertable/updatable=false). The reason for it was to avoid N+1 problem, and as far as I remember this was actually working. The field was lazily initilized without N+1 problem.

//…
public class EntityA {
    //…
    @BatchSize(size = 100)
    @ManyToOne(fetch = FetchType.LAZY)
    @JdbcTypeCode(Types.VARCHAR)
    @JoinColumn(name = "limit_id", insertable = false, updatable = false)
    private EntityB entityB;
}

the other side looked like:

//…
public class EntityB {
    //…
    @Setter(AccessLevel.NONE)
    @OneToMany(mappedBy = "entityB")
    @BatchSize(size = 100)
    private List<EntityA> entityAs;
}

But with hibernate 6 I’m getting:

Caused by: org.hibernate.AnnotationException: Property 'entityB' may not be annotated '@BatchSize'

was something changed? How things should be now, if we don’t want to go back to N+1 problem? Yes, I saw some comments, that this really never was supported, but I also saw comments, that it actually was on lazy loaded fields, and my memory is telling me that this was the case. Can someone advise?
