Hello,

I am upgrading from 6.1.7.Final.

I now have this error:

annotated ‘@NotFound’ is not a ‘@ManyToMany’ association

my join:

```auto
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "username", insertable = false, updatable = false)
@NotFound(action = NotFoundAction.IGNORE)
public MyPojo getDetail() {
	return detail;
}

```

I could find this change mentioned in the upgrade guide.

Is this correct? ie I have to remove all the @NotFound annotations?

Cheers

OK sorry, I found the answer in the list:

This annotation never did anything for `@OneToMany` or `@ManyToMany`, and we wanted to tell users to get rid of it, since it might be confusing to readers of the model, giving a wrong impression about behavior.
