Bắt đầu trong HttpProxyCacheServer.java tại closeSocketInput (dòng 280), releaseSocket (dòng 272) và processSocket (dòng 245), sử dụng stack trace được báo cáo làm điểm bắt đầu. Tái hiện đường dẫn tắt socket của Android 2.7.1 và xác định hành vi mong đợi khi thao tác tắt báo cáo ENOTCONN; hoàn tất khi hành vi được xử lý nhất quán mà không có lỗi đã báo cáo.
