嘿伙计我认为我发现了导致此错误的原因但我无法理解为什么或如何解决它。我尝试在两台Windows 7和一台Windows 8机器上运行此代码并获得相同的结果。错误并不总是发生，但有时会发生。这是我认为导致它的代码片段。
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？因为我在3台机器上试过它，我假设这不是硬件问题。有任何想法吗？非常感谢你们。

我无法找到问题的解决方案，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。
这用于监控目录。找到密钥后，正在处理和取消该密钥，然后在监视服务中添加了一个新密钥以继续监视同一文件夹。这并不总是导致致命的错误，但它平均每10次尝试中就有一次。
要解决这个问题，不是每次检测到更改时取消密钥，我只是轮询事件并使用密钥的reset（）方法将其重新添加到监视服务。
如果您要尝试此操作，请务必在重置之前从键中轮询（）事件。
关于错误。我仍然不知道为什么会发生这种情况但是我注意到，当你在C：/驱动器（在Windows中）的任何地方监视目录时，例如My Documents，它会发生。我试图监视USB驱动器中的文件夹，我无法重现错误（也许我没有尝试足够的次数）。我提交了一份错误报告。
