Trợ giúp với sự hiểu biết đầu ra jstack

Tôi có một ứng dụng Java/Swing trên máy tính để bàn được triển khai thông qua Java Webstart (các máy khách đang sử dụng Java 6u20 trên XP). Tôi đã nhận được các báo cáo liên tục từ người dùng ứng dụng đang treo. Tôi quản lý để đăng nhập vào một hệ thống như vậy trong một hang thấy rằng giao diện người dùng đã không được rút ra (như mặc dù EDT đã bị chặn).Trợ giúp với sự hiểu biết đầu ra jstack

Tôi đã sử dụng jstack để liệt kê các chủ đề; Tôi không thấy bất kỳ đề cập đến deadlocks trên đầu ra và kể từ khi tôi là khá mới để jstack tôi không chắc chắn những gì khác tôi nên tìm kiếm.

Tôi đã phải chỉnh sửa theo dõi ngăn xếp để cho phép nó phù hợp với giới hạn lưu lượng truy cập stackover, hy vọng không có ý nghĩa nào bị bỏ sót.

Cảm ơn,
Phil

Bạn đã có thể chạy vào lỗi 6960427, được báo cáo chống lại 1.6.0_20 (vấn đề khóa chết).

Bạn có chắc chắn rằng theo dõi ngăn xếp đã đăng đã hoàn tất chưa? Bạn có một số chủ đề chờ đợi để khóa trên 0x1d485f80, nhưng không có chủ đề với một khóa thực tế trên màn hình đó.

Dường như đây là một khóa khác gây ra sự cố nhưng có liên quan. –

Xin chào, xin lỗi vì sự chậm trễ trong trả lời, tôi vừa đọc các câu trả lời ngay bây giờ. Đối với các khóa trên 0x1d485f80, tôi snipped này alright, nó đang được tổ chức bởi thread 0x05913400. Có vẻ như sau: \t - bị khóa <0x1d485f80> (một com.sun.deploy.security.CPCallbackHandler $ ParentCallback) – PhilDin

[Vui lòng bỏ qua nhận xét ở trên, đây là ý định] Xin lỗi, xin lỗi vì sự chậm trễ trong trả lời, tôi vừa nhận được để đọc câu trả lời ngay bây giờ. Đối với các khóa trên 0x1d485f80, tôi snipped này alright, nó đang được tổ chức bởi thread 0x05913400. Có vẻ như sau: \t - bị khóa <0x1d485f80> (một com.sun.deploy.security.CPCallbackHandler $ ParentCallback) Tôi có đúng khi diễn giải điều này có nghĩa là loại đối tượng bị khóa là ParentCallback không? Nó trông giống như lỗi 6960427 nhưng tôi nhận thấy rằng trong báo cáo lỗi, nó liệt kê một bế tắc ở cuối, đầu ra jstack của tôi không xác định bất kỳ lỗi nào. – PhilDin

Có rất nhiều chủ đề tuyên bố

- waiting to lock <0x1d485f80> (a com.sun.deploy.security.CPCallbackHandler$ParentCallback)

Là tổ chức ở đâu đó trong đầu ra snipped?

Dường như bạn đang cố ý trộn mã đáng tin cậy và không đáng tin cậy ("mã hỗn hợp"), đó là một điều xấu. Từ 6u19 một hộp thoại cảnh báo được hiển thị (thực sự nỗ lực sẽ tự động bị chặn, nhưng dường như có rất nhiều mã ở đó khai thác lỗi). Đó là hộp thoại cảnh báo có vẻ như đang gây ra sự cố.

Để khắc phục, đừng trộn mã đáng tin cậy và không đáng tin cậy. Bạn nên thêm "Chỉ tin cậy: đúng" vào tệp kê khai của mỗi bình.

Xin chào Tom, tôi đã gặp sự cố với cảnh báo mã đáng tin cậy/không đáng tin cậy nhưng điều này không có chủ ý. Tôi đã ký tất cả các lọ (của riêng tôi + bên thứ ba) với một cert tự ký vì vậy tôi đã không mong đợi điều này là một vấn đề. Tôi có thể hỏi làm thế nào bạn có thể nói điều này từ đầu ra ngăn xếp (là nó là "16.3-b01 chế độ hỗn hợp, chia sẻ" dòng ở đầu?) Thứ hai, làm thế nào bạn có thể nói từ đầu ra rằng hộp thoại cảnh báo là vấn đề? Cảm ơn. – PhilDin

Dấu vết ngăn xếp bao gồm các lượt thích 'showMixedTrustDialog' và các chủ đề khác dường như đang chặn trong mã triển khai trong khi tải các lớp. "Chế độ hỗn hợp 16.3-b01" dùng để chỉ phiên bản HotSpot (hiện đã tách rời khỏi phiên bản JRE), thực tế là nó đang sử dụng cả trình biên dịch bytecode và trình thông dịch, và chia sẻ là "Chia sẻ dữ liệu lớp", đó là việc sử dụng các lớp '.tập tin jsa' cho hiệu suất khởi động nhanh hơn. Như tôi đã nói, nếu bạn thêm 'Chỉ tin cậy: đúng 'vào tệp kê khai của mình, thì điều đó sẽ tự động ngăn không cho tải mã không đáng tin cậy cho dù vô tình từ và đối thủ. –
