我们的应用程序中的自动崩溃报告器有时会在关闭应用程序时报告挂起。我们内部没有观察到这一点。 swing线程在ApplicationShutdownHooks.runHooks（）中挂起，我认为可能是因为WToolkit.shutdown（）永远不会返回。我不知道是什么造成的。任何人都可以帮我解决导致挂起的问题吗？这是一个完整的线程转储。谢谢！ JRE是1.6.0_35。

答案 0 :(得分：2)
我遇到了同样的问题，与JDK一起部署的JConsole程序也是如此。我正在寻找关于此的解决方案或错误报告，但它是从1.6.0_25开始的回归。以前的版本不会发生这个问题（我成功使用1.6.0_23）。
此论坛帖子是我找到此解决方法的地方：
