JVM崩溃了，我不明白为什么

Hey guys I think I have found what is caused this error but I can't understand why or how to fix it. I have tried running this code in two Windows 7 and one Windows 8 machine with the same results. The error doesn't always happen but it does sometimes. Here is the piece of code I think is causing it.

嘿，伙计们，我想我找到了导致这个错误的原因，但是我不知道为什么，也不知道如何去修复它。我试过在两台Windows 7和一台Windows 8机器上运行这段代码，结果是一样的。错误并不总是会发生，但有时确实会发生。这是我认为引起它的一段代码。

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;
    }
}

And this is the console output:

这是控制台输出:

Java Result: 1

As you can see, it never reaches the System.out.println("Done Making Key"); line. Does anyone understand why this is happening? Because I have tried it in 3 machines I am assuming this is not a hardware issue. Any ideas? Thank you a lot guys and girls.

正如你所看到的，它从来没有到达系统。println(“完成关键”);线。有人知道这是为什么吗?因为我在3台机器上试用过，所以我认为这不是硬件问题。什么好主意吗?谢谢大家。

I could not find a solution to my question but I found a work around. Let me explain how this was happening and how to achieve the same results.

我找不到问题的答案，但我找到了解决办法。让我解释一下这是如何发生的，以及如何实现同样的结果。

This was used to monitor a directory. Upon finding a key, that key was being processed and canceled, then a new key was added to the watch service to keep monitoring the same folder. This didn't always result in the fatal error but it did so in average in 1 out of 10 attempts.

这用于监视目录。找到一个密钥后，该密钥被处理并被取消，然后将一个新的密钥添加到watch服务，以继续监视相同的文件夹。这并不总是导致致命的错误，但平均每10次尝试中就有1次是这样。

To get around this, instead of canceling the key every time a change was detected, I am just polling the events and used the reset() method of the key to re-add it to the watch service.

为了解决这个问题，我只是轮询事件并使用key的reset()方法将其重新添加到watch服务中，而不是在每次检测到更改时取消键。

If you are going to attempt this, it is crucial that you poll() the events from the key before you reset it.

如果要尝试此操作，关键是在重置之前从键轮询()事件。

Regarding the error. I still don't know why it is happening but I have noticed that it happens some times when you are monitoring a directory anywhere in the C:/ drive (in Windows) such as My Documents. I tried to monitor a folder in a USB Drive and I couldn't reproduce the error (maybe I didn't try enough times). I submitted a bug report.

关于这个错误。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:/ drive (Windows)中的某个目录(比如我的文档)时，有时会发生这种情况。我试图监视USB驱动器中的一个文件夹，但无法重现错误(可能我没有尝试足够多的时间)。我提交了一个错误报告。
