【问题描述】：
我对 Java 安全性非常陌生，所以这个问题的答案可能很明显。我正在尝试在客户端和服务器之间执行简单的握手，我希望他们使用 TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 或 TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 进行握手。根据我阅读的所有地方，Java 8 支持这些密码，并且我已经安装了 JCE Unlimited Strength Jurisdiction Policy Files。因此，当我打印出 Java 安装中所有启用的密码时，这两个密码都存在，这意味着默认情况下它们是启用的。但由于某种原因，握手失败，因为客户端和服务器没有共同的密码套件。我也启用了 TLSv1.2 协议。客户端的公钥已导入服务器的信任库，其他密码（如 TLS_RSA_WITH_AES_128_CBC_SHA256 等）的握手成功。我正在运行 Java 8 v1.8.0_60。我还缺少什么？
