Java致命錯誤，不知道是什麼意思

它發生在我的代碼中的相同位置（雖然不是第一次執行該方法），但我不能做出錯誤的頭或尾。（雙倍，因爲它是機器人的代碼）。Java致命錯誤，不知道是什麼意思

如果有人能給我一個關於它是什麼樣的問題的想法，那就要最感激。我認爲這是與線程（多線程應用程序），但我真的不知道什麼？！？擔心uni項目的截止日期即將到來！

您是否擁有源代碼？這將有助於看到它。 – ponzao 2010-03-22 12:22:47

感謝您的回答，Ubuntu的包管理器沒有更新的JRE，但我更新了其他部分，現在它的作品。不能提供源代碼不幸，uni項目，所以我會妄想剽竊等 – 2010-03-22 14:42:09

「但我更新了其他部分」 - 哪些部分？我在debian（squeeze/sid）上遇到類似的問題，並認爲它是一個JVM錯誤，因爲GC線程發生異常，但是嘗試1.6_14到1.6_18，並且都顯示相同的行爲。 – Joel 2010-09-14 14:58:36

以下錯誤：

SIGSEGV (0xb) at pc=0xb70f0ca7, pid=5065, tid=2145643376

可見的地方，你訪問來自一個無效的內存ADRESS或NULL進程ID（5065）（此時不相關）。

所以，如果你正在編寫一個機器人，這意味着你要麼：

使用庫（DLL），可以到一個串行端口進行通信，以訪問機器人，你的代碼說話到庫可能傳遞一個NULL，然後在DLL中崩潰。
編寫您自己的本地庫，然後訪問NULL或無效的內存地址。

JVM然後崩潰。我不能進一步幫助你，因爲我不知道你的程序（用Java編程）如何與你的機器人通信，所以這只是一個調查。

瞭解SIGSEGV。

您正在運行Java 1.6.0修補程序15.根據發行說明，最新的修補程序版本（Java 1.6.0修補程序18）修復了大量JVM崩潰錯誤。所以這將是值得嘗試升級。

但是，你的問題是由flai JNI代碼引起的理論也是合理的。
