我有一个使用 Netty 调用 GRPC 服务的 Spring Boot 应用程序。当我在我的本地机器（没有 JCE 的 MacOS 和 zulu jdk）上运行我的代码时，我能够连接到 GRPC 服务。
注意：我们使用的是 Oracle JDK 1.8 编译的 GRPC 客户端 jar
当我构建一个 docker 映像（Alpine Linux with zulu jdk without JCE）时，出现以下错误

注意：顺便说一句，在我的本地它选择 TLS_ECDH_ECDSA_WITH_AES_128_GCM_SHA256
我将我的 java 版本降级为 Oracle JDK 1.8，并使用 JDK 1.8 构建了映像。现在我能够通过 SSL 握手解决问题，因为我可以看到图像中现在可用的所有密码。但是我最终遇到了一个非常 Alpine Linux 的问题。

看到这个https://github.com/grpc/grpc-java/issues/3336
我真的很想上zulu 11并想调用这个GRPC服务。我们是否应该只获取使用 JDK 11 编译的 GRPC 客户端 jar？
