Question

我有一个旧项目，试图修复其中的错误。有这样的代码（我仍然不完全了解其含义）：

SslContext sslCtx = SslContextBuilder
    .forClient()
    .trustManager(
        new FingerprintTrustManagerFactory(
            mySSLCertificate
        )
    ).build();

我正在尝试获取sslcontext，但是会定期发生错误：

        at io.netty.handler.ssl.JdkSslClientContext.newSSLContext(JdkSslClientContext.java:296)

如何解决？在哪里挖？

为什么创建SSLContext失败？
