Java 是否可以在htmlunit/webclient中设置cookie

我有这个代码，但我找不到最好的解决方案。我不知道饼干的那一面。这是代码和警告Cookie

在我使用getPage下载一个文件并将其写入我的目录之后，我尝试登录该网站

String url = "https://www.frw.co.uk/login";
    final WebClient webClient = new WebClient(BrowserVersion.INTERNET_EXPLORER_10);

    webClient.getOptions().setRedirectEnabled(true);
    webClient.getOptions().setCssEnabled(false);
    webClient.getOptions().setThrowExceptionOnScriptError(false);
    webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
    webClient.getOptions().setUseInsecureSSL(true);
    webClient.getOptions().setJavaScriptEnabled(true);
    webClient.getCookieManager().setCookiesEnabled(true);
    java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(Level.OFF);

    try {

        HtmlPage login = webClient.getPage(url);//button.click();

        final HtmlForm form = (HtmlForm) login.getElementById("loginForm");

        form.getInputByName("j_username").setValueAttribute("example@hotmail.com");
        form.getInputByName("j_password").setValueAttribute("examplepassword");

        HtmlPage reslogin = form.getInputsByValue("Login").get(0).click();

        //reslogin = webClient.getPage("https://www.frw.co.uk/excel/download");

        HtmlPage downloadPage = reslogin.getAnchorByText("Download Wine List").click();

        downloadPage = webClient.getPage("https://www.frw.co.uk/excel/download");


        WebResponse response2 = downloadPage.getWebResponse();
        InputStream is = response2.getContentAsStream();
        OutputStream outputStream = new FileOutputStream(new File(fileTarget));

        int read = 0;
        byte[] bytes = new byte[1024];

        while ((read = is.read(bytes)) != -1) {
            outputStream.write(bytes, 0, read);
        }
        outputStream.flush();
        outputStream.close();

        System.out.println("Cookie "+webClient.getCookieManager().getCookies());

        System.exit(1);
    } catch (Exception e) {
        e.printStackTrace();
    }

    webClient.closeAllWindows();

警告结果：

cookie管理器抛出警告。请参阅。INTERNET_EXPLORER_10表示您使用的是旧的HtmlUnit版本，请使用最新的2.19，然后重新发布您的问题。我已更新了HtmlUnit版本，但cookie仍被拒绝。在这件事上我真的很难过。
