### Ⅲ. Describe what you expected to happen

### Ⅳ. How to reproduce it (as minimally and precisely as possible)

1. xxx
2. xxx
3. xxx

### Ⅴ. Anything else we need to know?

### Ⅵ. Environment:

- JDK version :11
- OS :w10
- Others:

Start by tracing how @Reference services are discovered by GlobalTransactionScanner and where TccActionInterceptor is created in Seata 1.3. The issue provides no reproduction steps, exception, or named files, so first establish a minimal case on JDK 11 and determine whether the service is expected to be scanned.
