我知道正在运行的线程数量很多，但是没有一个可以解决此问题。我正在尝试使用selenum获取aspx页面。但是它在这行代码中抛出UnreachableBrowserException
WebDriver driver = new ChromeDriver();。chrome实例正在打开，但随后几秒钟后，它抛出了我上面提到的异常。

这是我的示例代码。

System.setProperty("webdriver.chrome.driver", 
           "C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");

        WebDriver driver = new ChromeDriver();
        driver.get("http://some aspx page with form");
            System.out.println("!!!!! Got the page !!!!!");
            driver.close();
            driver.quit();

以下是堆栈跟踪。
