我将 Restlet 2.1.2 和 2.2 M3 与 Jetty 一起用于 https（也使用了简单框架）。我使用的证书由 Comodo 签名。
我已将 AddTrust 根证书和 Comodo 中间证书添加到jre/lib/security/cacerts（openjdk 7）。为了确保它们是正确的，我在向服务器发出请求后从 Firefox 导出了它们。我使用 cacerts 作为信任库，并且我有另一个密钥库文件，其中添加了证书和私钥。
正如我所提到的，在向服务器发出 https 请求之前，我最初使用的是 Firefox。Firefox 得到答案，证书有效并被接受。尽管服务器已经发送了答案，但它似乎无法正确处理连接。
这是我认为有趣的日志的一小部分（调试模式）：

并且服务器似乎继续使用像这样的几条日志行：FINER：Handling SSL handshake：NOT_HANDSHAKING
之后，我尝试从存折 iPhone 应用程序（这旨在成为存折 Web 服务）进行连接，并且服务器似乎进入了无法退出的循环。

而这个循环似乎是无穷无尽的。此外，CPU 负载达到 100%。
