Swing アプリケーションで Nimbus ルック アンド フィールを使用しています。
(dialog.setVisible(true) を使用して) ダイアログが表示されると、Nimbus のルック アンド フィールが次の例外をスローすることがあります。

これがいつ発生するかはわかりませんが、ダイアログが表示されているときはめったに発生しません。
私は Google ( http://netbeans.org/bugzilla/show_bug.cgi?id=212757 ) で検索してきましたが、より多くの人に発生しましたが、誰もこの問題の原因を知らないようです。
これは他の誰かに起こりましたか？多分それはニンバスのバグですか？
