    assertThatExceptionOfType(Exception.class).isThrownBy(q::getSingleResult).withMessageContaining("closed");
    // We would typically expect an IllegalStateException, but Hibernate throws a
    // PersistenceException. So we assert the contents of the exception message instead.
    Query q2 = em.createQuery("select p from Person as p");
    q2.setFlushMode(FlushModeType.AUTO);
    assertThatExceptionOfType(NoResultException.class).isThrownBy(q2::getSingleResult);
