远程事务没有回滚

大神，请教一个问题，先调用远程事务，远程事务正确，再调用本地事务，本地事务报错，能回滚，远程事务不回滚，怎么处理？

本地事务代码如下：
@LcnTransaction(propagation = DTXPropagation.REQUIRED)
@Transactional//事务注解
public ReturnMap save(HttpServletRequest request, HttpServletResponse response,TeacherAttrBean teacherAttrBean){
JSONObject jsonObject = JSONObject.fromObject(sysFegin.saveUserInfo(teacherAttrBean));
System.out.println(1/0); // 抛出异常
}

// 远程事务
@TccTransaction(propagation = DTXPropagation.SUPPORTS)
@Transactional
public ReturnMap saveUser(HttpServletRequest request, HttpServletResponse response,UserBean userBean) {
// 插入数据库 代码省略
return ok
}

Start with the `save` and `saveUser` entry points shown in the issue, focusing on their `@LcnTransaction`, `@TccTransaction`, and `@Transactional` annotations. Reproduce the remote call followed by the local `1/0` exception, then read the transaction propagation and rollback documentation or tests; done means the expected rollback behavior and configuration are clearly established.
