## Describe what happened?
在A服务中执行使用@GlobalTransactional修饰的方法，调用B服务的方法时报错；去掉@GlobalTransactional，程序正常运行

## Environment
- JDK version : 1.8.0_121
- OS :Win10 15063.0
- Others: Nacos 1.4.0、Seata1.3.0、SpringBoot 2.3.2、MyBatis 3.3.2

Start with the reported INSERT in DictionaryInfoMapper.xml and the copyDefaultSchoolInfo entry point, then trace the failure through ExecuteTemplate.execute and DictionaryInfoService.copyDefaultInfo2CurrentSchool. Reproduce the school-creation flow and determine the cause of the Seata ShouldNeverHappenException; done means the operation succeeds and the failure has regression coverage.
