我在一个使用 SSL 连接到外部 API（Zendesk API）的应用程序上工作。
它以前工作正常，但现在每当应用程序尝试连接到 Zendesk API 时，我们都会收到以下错误：java.net.ConnectException: Error constructing implementation (algorithm: Default, provider: SunJSSE, class: sun.security.ssl.SSLContextImpl$DefaultSSLContext)由NoClassDefFoundError: Could not initialize class sun.security.ssl.SSLContextImpl$DefaultManagersHolder.
我们在 Debian 8.11 上使用 Java 1.7.0_231。
我在互联网上找不到任何解决方案。
我检查了凭据：它们是正确的。
从我在互联网上发现的内容来看，这个错误可能是由于缺少 jar “jsse.jar”引起的，但我已经检查过它存在。
它适用于另一个环境，即带有 java 1.7.0_211 的 Debian 9.9。
这是堆栈跟踪：
