Java 7 Update 5 以降、私の Java Web Start アプリケーションは接続を確立する許可を要求しています。アプリケーションは有効な証明書で署名されています。

次のテキストを含むポップアップが表示されます。

アプリケーションは、www.example.com への接続を確立する許可を要求しました。この操作を許可しますか? [OK] [キャンセル]

リクエストを拒否すると、コンソールに次のトレースが表示されます。

アプリケーションは、Web サイトから画像を取得するウェルカム画面で構成されます。この画面は閉じられ、メイン アプリケーション ウィンドウが表示されます。警告は、ようこそ画面が表示される前にのみ表示されます。アプリケーションが開始されると、アプリケーションによって開始されたいくつかの接続にもかかわらず、他の警告は表示されません。

この問題の原因は何ですか? これは Java 7u5 のリグレッションですか、それとも新しい機能ですか? これについては、リリース ノートで言及されていません。

ありがとうございました

セキュリティポップアップと組み合わせて、デッドロックを引き起こすこともあります。(他のウェブスタートのバグのため)。これは、リリース ノートの 7u5 での 7177094 の「修正」が原因である可能性が最も高いです。バグ # 7177349 についてこのコメントをしようとしましたが、コメントはありませんでした。
