无法处理浏览器窗口（htmlunit）

Question

我想从网站下载 config.bin 文件。使用htmlunit

final WebClient webClient = new WebClient(BrowserVersion.CHROME);
webClient.getOptions().setTimeout(2000);
webClient.getOptions().setThrowExceptionOnScriptError(false);
webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);

webClient.setConfirmHandler(new ConfirmHandler() {
    public boolean handleConfirm(Page page, String message) {
        System.out.println(" -----------------------");
        System.out.println("handle config");
        System.out.println(" -----------------------");
        return true;
    }
});
final HtmlPage page = webClient.getPage("http://site");
final DomElement backup = mainFrame.getElementByName("Backup");
        webClient.addWebWindowListener(new WebWindowListener()
        {
            public void webWindowClosed(WebWindowEvent event)
            {
                System.out.println("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1");
            };

            public void webWindowContentChanged(WebWindowEvent
                                                        event)
            {
                System.out.println("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!2");
            }

            public void webWindowOpened(WebWindowEvent event)
            {
                System.out.println("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!3");
            }
        });

        InputStream input = backup.click().getWebResponse().getContentAsStream();    

然后提交ckick()我认为获取流，但获得了提交页面。我认为我的浏览器窗口有问题，我无法处理浏览器窗口。我在处理程序中插入sout，看看此方法何时被调用，但它没有调用

问题出在我安装的时期。已更改setTimeout并且全部正常工作。

webClient.getOptions().setTimeout(15000);
