Bắt đầu trong module shardingsphere-spi tại RequiredSPIRegistryTest.java, đặc biệt là assertRegisteredServiceNotExisted ở dòng 40, và tái hiện lỗi bằng mvn test khi tính năng ghi đang được bật. Truy nguyên lý do test nhận được NullPointerException thay vì ServiceProviderNotFoundException, sau đó xác minh rằng các test của module đều chạy qua khi Java agent đang hoạt động.
