我刚刚从以前的 rc5 更新到 restlet rc6。android 应用程序对外部 url 进行简单的 https 调用。

在 rc5 中一切正常，在 rc6 中我现在收到以下错误：

谁能告诉我 rc6 中发生了什么变化使其不再工作？

rc6 的发行说明说：

The support for HTTPS has been significantly completed and fixed in all connectors for :

cipher suites restriction
SSL/TLS protocol version restriction
client certificate request & requirement setting

不幸的是，我在官方文档中没有找到任何提示，我的代码需要更改哪些内容才能让它再次工作。

谢谢，蒂洛

愚蠢的兔子DefaultSslContextFactory.createSslContext(..)显然在 rc6 的方法中包含以下内容：

setKeyManagerAlgorithm(helperParameters.getFirstValue(
            "keyManagerAlgorithm", true, System.getProperty(
                    "ssl.KeyManagerFactory.algorithm", "SunX509")));

即，他们对 Sun JDK 专有的 SunX509 进行了硬编码——总体而言，这是一个非常糟糕的主意。025d356d9fc3620ba9ed613fed32f1a5668f4f70这已在17 天前的 commit 中修复。

如果您现在需要它来工作，您当然可以尝试自己下载和构建库。
