在java代码中显示异常（Selenium+；Jsoup）

我正在做一个项目。在这方面，我必须得到HTML页面的源代码。为此，我使用

Selenium

调用firefox驱动程序，并以字符串形式存储页面源代码，然后使用

Jsoup

我的代码在单个

url

上运行良好。但是当我把我的代码放在测试中，它必须一个接一个地获取URL的数量，然后在最后它抛出一个异常，我的项目失败了。请查看异常并告诉我发生这种情况的原因，并给我一些解决方案来克服此异常

我的selenium代码如下所示，

private static FirefoxProfile createFirefoxProfile() {
    File profileDir = new File("/tmp/firefox-profile-dir");
    if (profileDir.exists()) {
        return new FirefoxProfile(profileDir);
    }
    FirefoxProfile firefoxProfile = new FirefoxProfile();
    File dir = firefoxProfile.layoutOnDisk();
    try {
        profileDir.mkdirs();
        FileUtils.copyDirectory(dir, profileDir);
    } catch (IOException e) {
        e.printStackTrace();
    }
    return firefoxProfile;
}
