サーバーはTomcat 7ベースのアプリであり、Java 7、Linux、およびAmazon EC2で実行する価値があります。
SSL以外のポートへの偶発的な接続など、考えられる原因について多くの提案を見つけました。主にまったく同じクライアントが機能するため、すべてを排除したと思います。変更なしでJava 7を実行する場合。 (どちらの場合もOSX。)
以下に、Java 6およびJava 7のSSL接続手順からのデバッグ出力を含めます。専門家への私の質問は、これは、可能性のある暗号またはプロトコル設定、おそらくJava 7のデフォルトがJava 6で有効にして動作することを示唆していますか?

ブルーノの答えは最終的に正しいものでした。これは、https.protocols
システムプロパティによって最も簡単に制御されます。これは、ファクトリメソッドが返すものを制御する方法です。たとえば、「TLSv1」に設定します。
クライアントSSLSocketまたはHttpsURLConnectionの有効なプロトコルから「SSLv2ClientHello」を削除します。
サーバーの引数を-Dhttps.protocols = SSLv3から-Dhttps.protocols = TLSv1、SSLv3に更新します
次のようにします:
SSLSocket socket = (SSLSocket) sslFactory.createSocket(Host, port);
socket.setEnabledProtocols(new String[]{"SSLv3", "TLSv1"});
