我正在通过 Google Cloud Java 客户端库使用 Google DLP，当我升级到最新版本 0.44.0-beta 时，我开始得到CertificateException如下所示的内容。当我在带有 Oracle JDK 8 的 Mac 上运行它时，它运行良好，但是当在 Docker 实例中的 OpenJDK 8 中运行时，我看到了异常。我必须在 OpenJDK 上运行它。我猜证书是由 OpenJDK 未知的 CA 签署的。最简单的解决方案是什么？我是否必须为 OpenJDK 安装自定义 CA？有趣的是，OverOps 快照包含对这个方法的调用：
public io.grpc.netty.shaded.io.netty.handler.ssl.util.SelfSignedCertificate(String fqdn, SecureRandom random, int bits, Date notBefore, Date notAfter)
并且fqdn参数实际上设置为example.com。堆栈跟踪如下：
