getSingleResult（）导致NoResultException上的回滚

Question

我在Wildfly 14上运行的应用程序中使用容器管理的事务。

由于意外的事务回滚，以下代码失败：

@Transactional
public User example(...) {
    User user = findUserByName(...);
    // ...
}

private User findUserByName(String username) {
    try {
        User user = userDao.findUserByName(username); // throws NoResultException
        // ...
        return user;
    } catch (NoResultException e) {
        List<User> users = userDao.getAll(); // throws SQLException: Transaction cannot proceed: STATUS_MARKED_ROLLBACK
        // ...  
    }
}

阅读NoResultException的JavaDoc，该合同明确规定：

  

此异常不会导致当前事务（如果正在进行）被标记为回滚。

显然，由于getAll()（或任何其他查询）引发异常的根本原因是，事务仍被回滚：

userDao.findUserByName只需执行以下操作：

public User findUserByName(String username) {
    return em.createNamedQuery("User.findByName", User.class)
            .setParameter("name", username)
            .getSingleResult();
}

我缺少一些配置吗？我什至尝试了@Transactional(dontRollbackOn = {NoResultException.class})（不知道它是否在容器管理的交易中起任何作用），但没有成功。
