我想我已经找到导致此错误的原因，但我不明白为什么或如何修复它。我曾尝试在两台 Windows 7 和一台 Windows 8 机器上运行这段代码，结果相同。错误并不总是发生，但有时会发生。这是我认为导致它的一段代码。
private WatchKey registerPath(Path path) {
try {
System.out.println("Making Key for: " + path.toString());
System.out.println("ChangesWatcher: " + changesWatcher);
WatchKey key = path.register(changesWatcher,
StandardWatchEventKinds.ENTRY_MODIFY,
StandardWatchEventKinds.ENTRY_DELETE,
StandardWatchEventKinds.ENTRY_CREATE);
System.out.println("Done Making Key");
return key;
} catch (Exception err) {
err.printStackTrace(System.out);
return null;
}
}
这是控制台输出:
Making Key for: C:\Users\Fiona\Simple Cloud
ChangesWatcher: sun.nio.fs.WindowsWatchService@2be33a92

如您所见，它永远不会到达 System.out.println("Done Making Key");线。 有谁知道为什么会这样？因为我已经在 3 台机器上试过了，所以我假设这不是硬件问题。有任何想法吗？非常感谢你们。

最佳答案
我找不到问题的解决方案，但我找到了解决方法。让我解释一下这是如何发生的以及如何实现相同的结果。
这用于监视目录。找到 key 后，将处理并取消该 key ，然后将新 key 添加到监视服务以继续监视同一文件夹。这并不总是会导致 fatal error ，但平均每 10 次尝试中就有 1 次会导致 fatal error 。
为了解决这个问题，我不是在每次检测到更改时都取消 key ，而是轮询事件并使用 key 的 reset() 方法将其重新添加到监视服务。
如果您要尝试这样做，请务必在重置之前轮询()键中的事件。
关于错误。我仍然不知道为什么会发生这种情况，但我注意到当您监视 C:/驱动器(在 Windows 中)中的任何目录(例如我的文档)时，有时会发生这种情况。我试图监控 USB 驱动器中的文件夹，但我无法重现错误(也许我没有尝试足够的次数)。我提交了错误报告。
关于java - JVM 崩溃了，我不明白为什么，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17803085/
