java Tomcat webapp 错误 - 应用程序启动线程 [AWT-Windows] 但未能阻止它 - 内存泄漏？

Tomcat webapp error - application started thread [AWT-Windows] but has failed to stop it - memory leak?

提问by katura

I didn't notice it until today during some testing locally on my pc, that Tomcat had posted an error in the log file. I'm using Tomcat 6.0.29 and Java JDK 1.6.

直到今天在我的电脑上进行本地测试时，我才注意到 Tomcat 在日志文件中发布了一个错误。我使用的是 Tomcat 6.0.29 和 Java JDK 1.6。

Dec 1, 2010 12:36:57 pm org.apache.catalina.core.StandardContext reload INFO: Reloading this Context has started Dec 1, 2010 12:36:57 pm org.apache.catalina.loader.WebappClassLoader clearReferencesThreads SEVER: The web application [/AutoSpyder] appears to have started a thread named [AWT-Windows] but has failed to stop it. This is very likely to create a memory leak.

This is very likely to create a memory leak.

What? I've never seen this before. So I checked my log file from yesterday, and sure enough, this error was there too. I don't quite understand what's causing this.

什么？我以前从未见过这个。所以我检查了我昨天的日志文件，果然，这个错误也存在。我不太明白是什么原因造成的。

Can I assume that it would have to be one of my servlets that uses objects from the java.awtpackage?If so, how do I pinpoint the code that is causing this?

我可以假设它必须是使用java.awt包中对象的 servlet 之一吗？如果是这样，我如何查明导致这种情况的代码？

Try taking a thread dump to get a list of all the threads running on your server. From this, you may be able to pinpoint exactly which class started the thread based on the stack traces

尝试进行线程转储以获取服务器上运行的所有线程的列表。由此，您可以根据堆栈跟踪准确指出哪个类启动了线程

It looks like you are running JMX and I'm getting the impression that the Tomcat JMX server may be what's actually setting up the timer thread. In addition to the ones you mentioned in your parallel post on the JavaRanch, there's a java2D thread in the dump you have here.

看起来您正在运行 JMX，我的印象是 Tomcat JMX 服务器可能是实际设置计时器线程的原因。除了您在 JavaRanch 的并行帖子中提到的那些之外，您在此处的转储中还有一个 java2D 线程。

I can't tell 100% because I don't know which threads were the parents for the orphan threads. If you could determine that, it would help.

我不能说 100%，因为我不知道哪些线程是孤儿线程的父线程。如果您能确定这一点，那将有所帮助。

Your Affine Transform is definitely pulling in graphics, however. It's a graphical function that will attempt to use your video card as a hardware accelerator. If you don't specify headless operation, it will tap into your windowing system to do so.

但是，您的仿射变换肯定会引入图形。这是一个图形功能，将尝试将您的视频卡用作硬件加速器。如果您不指定无头操作，它将进入您的窗口系统来执行此操作。

Inspired by this threadI found the following solution:

受此线程的启发，我找到了以下解决方案：

You only need to attach the AWT-Window-Thread to System-Classloader instead to Wabapp-Classloader. You can do it in a ServletContextListener like this:

您只需要将 AWT-Window-Thread 附加到 System-Classloader 而不是附加到 Wabapp-Classloader。您可以在 ServletContextListener 中这样做：

public void contextInitialized(ServletContextEvent evt) {
    Thread thread = Thread.currentThread();
    ClassLoader ccl = thread.getContextClassLoader(); // PUSH
    try {
        thread.setContextClassLoader(ClassLoader.getSystemClassLoader());
        Toolkit.getDefaultToolkit().createImage(new byte[]{});
    } finally {
        thread.setContextClassLoader(ccl); // POP
    }
}

It's to do with Windows (i.e. MS Windows) and native calls to the underlying OS. These would normally be GUI-type window operations, but could be other OS-specific things, e.g Clipboard or Font related, for instance.

它与 Windows（即 MS Windows）和对底层操作系统的本机调用有关。这些通常是 GUI 类型的窗口操作，但也可能是其他操作系统特定的东西，例如与剪贴板或字体相关的东西。

If there's nothing obvious that you can see in your code that might relate to why it's being triggered, though, I'd not worry about it - that warning's more for the general case where spinning off new threads in a web-app isn't something you should be explicitly doing without a full appreciation of the potential issues.

但是，如果您在代码中看不到任何可能与触发原因有关的明显内容，那么我不会担心 - 该警告更多用于一般情况下在网络应用程序中分离新线程不是您应该在没有充分了解潜在问题的情况下明确做的事情。

We have tomcat server and jsf. JSF client will request images from the server and cause AWT-Windows thread to get started. Appears to cause a memory leak since threads contextClassLoader is the WebappClassLoader.

我们有 tomcat 服务器和 jsf。JSF 客户端将从服务器请求图像并启动 AWT-Windows 线程。似乎会导致内存泄漏，因为线程 contextClassLoader 是 WebappClassLoader。

Looks like calling Java2DResource can caused AWT-Windows thread to be created -

看起来调用 Java2DResource 会导致创建 AWT-Windows 线程 -
