如何解释Java线程堆栈？
符合这个问题： 如何获得线程的堆栈跟踪
我想知道是否有人可以指出有关解释用jstack提取的Java线程堆栈的信息。
我的情况是我在GlassFish v2.1.1上运行的Java EE 5应用程序定期挂起（每天至少2-3次）。为了让它再次运行，我必须杀死Glassfish进程并再次启动域。 应用程序通常会变得越来越慢，直到它最终完全挂起。 一旦挂起，我就无法获得线程堆栈。 我已经能够获得一个线程堆栈，因为它越来越慢，但我看不到找到问题或挂起的线程。

我正在寻找有关解释转储的一般信息，以便我可以在将来诊断问题。 谢谢。
一些可能对你有帮助的事情
- 以下是不同的线程状态，如BLOCKED，WAITING等。
- Java将为您找到死锁，您将看到如’使用’jstack’检测Java线程死锁中所述的输出。
- 你可能有一个活锁 。 在这里，您需要有关系统的信息并通过转储和源代码。
如何推进当前的问题？
- 根据这个转储，我可以告诉你有几个对象被锁定并等待多个线程。 寻找字符串’ – 等待’和’ – 锁定’。 我不知道你的应用程序的逻辑更多。
从你的线程转储：

看起来你在JDK中使用Selector旋转时有着名的BUG。
