 Post subject: cascade="all-delete-orphan" was no longer referenced

I'm getting the error:

org.hibernate.HibernateException: A collection with cascade="all-delete-orphan" was no longer referenced by the owning entity instance: house.datamodel.User.roles

Now I've read the doco, and it says not to replace any collections. But I'm not. I even declared my collections to be final, just to make sure they're not.

The scenario is Users and Roles, that everyone is probably familiar with in a JEE web server:

The error happens in various scenarios, including queries, but it even happens if I don't actually modify any objects, and then it happens on commit.

Code:
drop table roles;
drop table users;

create table users (
user_id varchar(100) constraint user_pk primary key,
name varchar(100) not null,
password varchar(100),
email varchar(100)
);

create table roles (
user_id varchar(100) not null constraint role_user_fk references users(user_id) on delete cascade,
role_id varchar(100) not null,
constraint user_role_pk primary key(user_id, role_id)
);
