java-me - java.lang.NullPointerException at com.sun.lwuit.html.CSSEngine.applyStyleToUIElement (不明なソース)

Question

j2me用のEclipse pulsarでS60 SDKを実行しています。Linkedn ログイン ページを読み込もうとしています。しかし、htmlc.setPage() を設定してlinkedin.comのみをロードすると取得できず、今すぐリンクされた名前の参加のみが表示されます..しかし、電子メールとパスワードのテキストボックスとログインボタンは表示されません。

以下に示す私のクラスコード：

public class Login {
    Form form = new Form();
    String authorizeUrl = "";
    LinkedInUser user;

    public Form Login() {
        try {
            Display.init(this);
            HttpRequestHandler  handler = new HttpRequestHandler();// = new AsyncDocumentRequestHandler();
            HTMLComponent htmlC = new HTMLComponent(handler);
            user = new LinkedInUser(Const.consumerKey, Const.consumerSecret);
            user.fetchNewRequestToken();

            if (user.requestToken != null) {
                authorizeUrl = "https://www.linkedin.com/uas/oauth/authorize?oauth_token="
                        + user.requestToken.getToken();
            }
            //htmlC.setPage("http://m.google.com");
            System.out.println(""+htmlC.toString());
            System.out.println(""+authorizeUrl);

            //htmlC.setPage("https://www.linkedin.com/uas/oauth/authorize?oauth_token=5a7ed20d-3a04-419d-85ea-ba99fc06ddbd");
            htmlC.setPage(authorizeUrl);
            System.out.println(authorizeUrl);
            FlowLayout flow = new FlowLayout(Component.TOP);
            form.setLayout(flow);
            form.addComponent(htmlC);



            //myMIDlet.platformRequest("http://wap.mdfactory.com");

        } catch (Exception e) {
            e.printStackTrace();
        }

        return form;
    }
}

次の一連のエラーが発生します。
