Java 8可正常建立SSL连接，Java 17连接失败求助

我在通过SSL(TLS)连接调用REST API时遇到问题，持有数据提供方的私钥和签名证书，已用这些文件创建密钥库(keystore)，并通过代码构建SSLContext，在与提供方服务器建立HTTP连接时使用该上下文。目前的问题是：Java 8下可正常建立连接，但Java 17下握手失败。

我想知道遗漏了什么？Java 8的证书是否兼容Java 17？我了解到Java 17引入了TLSv1.3，但使用该版本时SSL握手同样失败。尝试过Java 11和Java 17，发现仅Java 8下的SSLContext可正常工作并获取REST响应。

恳请有类似经验或了解可能原因的人士提供帮助。以下是日志片段（端点已掩码）：
