### 4. Tour Idea

Tái hiện lệnh gọi đa cấp A-B-(C, D, E) với các phiên bản CentOS và dependency được báo cáo, sau đó lần theo quá trình giải tuần tự hóa từ txmsg/netty/handler/ObjectSerializerDecoder.java qua common/util/serializer/ProtostuffSerializer.java. Kiểm tra lỗi tải lớp của Protostuff RuntimeEnv đối với JpaSystemException; hoàn tất khi lệnh gọi được báo cáo không còn gây ra ClassNotFoundException này.

Do mô hình lập chỉ mục viết ra từ nội dung của issue.
