Report a typo

There are the following two entities:

@Entity
public class PublishingPlatform {

    @Id
    private int id;

    @OneToMany(mappedBy = "platform", cascade = CascadeType.REMOVE)
    private List<Post> posts;
}

@Entity
public class Post {

    @Id
    private int id;

    @ManyToOne
    @JoinColumn(name = "platform_id")
    private PublishingPlatform platform;
}

What happens to all Posts connected to an instance of a PublishingPlatform, if we delete the row corresponding to this instance from the PublishingPlatform table?
