Java applet, Java AWTのエラーについて

前提・実現したいこと

Eclipse環境でJava applet, Java AWTでスマホで注文できる小型店舗チェーンもどきをいじろうとしています。

流れは
1.商品選択
2.数量の変更
3.クレジットカードの情報の入力画面（あくまで形だけです。）
4.領収書の画面
5.エラーがあった場合、エラー画面の表示
です。

この中でクレジットカードの入力画面で、クレジットカードの番号・所有者の名前・有効期限を入力しようとすると以下のエラー画面が出てしまいます。
エラーの意味と、改善策をご教示頂きたいです。

エラーコード及びソースコードの量が多いのですがよろしくお願いします。

同じソースコードでWindows環境下でのEclipseだと実行できました。
自分が使っているのはMac環境なのでそのせいもあるかもしれません。
