Just add @Transactional annotation on your method, e.g.

@Transactional // <-------------
public long setSessionState(StateEnum state, String hash) {

    QSession s = QSession.session;
    JPAUpdateClause upd = new JPAUpdateClause(em, s);
    upd.set(s.state, state).where(s.hash.eq(hash));
    return upd.execute();
}
