https用のJettyでRestlet 2.1.2および2.2 M3を使用しています（Simple Frameworkも使用しています）。私が使用している証明書は Comodo によって署名されています。
AddTrust ルート証明書と Comodo 中間証明書の両方をjre/lib/security/cacerts(openjdk 7) に追加しました。それらが正しいものであることを確認するために、サーバーにリクエストを行った後、Firefox からそれらをエクスポートしました。トラストストアとして cacerts を使用しており、証明書と秘密鍵を追加した別のキーストア ファイルがあります。
前述のように、サーバーに https リクエストを送信する前は、最初は Firefox を使用していました。Firefox は応答を取得し、証明書は有効で受け入れられます。ただし、サーバーは応答を送信しましたが、接続を適切に処理できないようです。
興味深いと思われるログ (デバッグ モード) の一部を次に示します。

そして、サーバーは次のようないくつかのログ行で作業を続けているようです: FINER: Handling SSL handshake: NOT_HANDSHAKING
その後、通帳のiPhoneアプリ（通帳のWebサービスを目指しています）から接続しようとしたところ、サーバーが抜け出せないループに陥ってしまったようです。

そして、このループは無限にあるようです。また、CPU 負荷が 100% に達します。
