帮助理解jstack输出

我有一个桌面Java/Swing应用程序通过Java Webstart（客户端在XP上使用Java 6u20）进行部署。我收到了挂起应用程序用户的间歇性报告。我设法在挂起期间登录到这样的系统，发现UI未被绘制（就像EDT被阻止）。帮助理解jstack输出

我用jstack来列出线程;我没有看到任何关于输出的死锁，因为我对jstack很陌生，我不知道我应该找什么。

我不得不编辑堆栈跟踪以允许它适合在stackoverflow限制内，希望没有任何重要性被遗漏。

感谢，
菲尔

你可能遇到的bug 6960427，这是对报道1.6.0_20（死锁问题）。

是否确定发布的堆栈跟踪已完成？您有几个线程正在等待锁定在0x1d485f80上，但没有在该监视器上实际锁定的线程。

它似乎是一个不同的锁造成的问题，但相关。 – 2010-08-26 15:32:13

您好，对于延迟回复表示歉意，我现在只需阅读回复。关于0x1d485f80上的锁，我将这一切都修剪好了，它正在由线程0x05913400保存。它看起来如下：\t - 锁定<0x1d485f80>（一个com.sun.deploy.security.CPCallbackHandler $ ParentCallback） – PhilDin 2010-09-06 09:06:45

[请忽略上述评论，这是预期的]嗨，道歉延迟回复，我刚刚现在阅读回复。关于0x1d485f80上的锁，我将这一切都修剪好了，它正在由线程0x05913400保存。它看起来如下：\t - 锁定<0x1d485f80>（一com.sun.deploy.security.CPCallbackHandler $ ParentCallback）我说得对在训释这意味着被锁定对象的类型是ParentCallback？它看起来类似于错误6960427，但我注意到在错误报告中，它在最后列出了一个死锁，我的jstack输出没有识别任何错误。 – PhilDin 2010-09-06 09:17:26

有自称

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

很多线程的是，在剪断输出召开地方？

看起来像你故意混合可信和不可信代码（“混合代码”），这是一件坏事。从6月19日显示一个警告对话框（实际上应该自动阻止尝试，但似乎有大量的代码利用该错误）。这是警告对话框，似乎是导致问题。

要解决问题，请不要混用可信代码和不可信代码。将“Trusted-Only：true”添加到每个jar的清单中是一个好主意。

嗨汤姆，我遇到了可信/不可信代码警告的问题，但这不是故意的。我已经用自签名证书签署了所有的罐子（我自己的+第三方），所以我没有想到这会是一个问题。我可以问一下，如何从堆栈输出中得知这一点（是否是顶部的“16.3-b01混合模式，共享”行？）其次，您如何从输出中指出警告对话框是问题？谢谢。 – PhilDin 2010-09-06 09:42:31

堆栈跟踪包括诸如'showMixedTrustDialog'之类的东西，其他线程在加载类时似乎在部署代码中被阻塞。 “16.3-b01混合模式，共享”是指HotSpot的版本（现在与JRE版本分离），它使用字节码编译器和解释器，共享的事实是“类数据共享”，这是使用'类。jsa文件，可以提供更快的启动性能。正如我所说的，如果您向您的清单中添加“Trusted-Only：true”，那么应该默默地防止加载不受信任的代码，无论是无意识的还是来自对手。 – 2010-09-06 12:21:48
