Java 11 SSL 异常:找不到所请求目标的有效证书路径

Question

在尝试将我的一个应用程序从java 8升级到java 11的过程中，我遇到了一个奇怪的SSL异常，关于"找不到有效的认证">

此应用程序的配置会使用包中的cacerts覆盖默认ca-certificates-javaJDK/JREcacerts，因此在升级之前和之后，密钥存储中的证书应相同(这也使用keytools进行验证)：

# java 8
ls -l /usr/lib/jvm/java-1.8.0/jre/lib/security/cacerts
lrwxrwxrwx 1 root root 41 Sep 11 22:52 /usr/lib/jvm/java-1.8.0/jre/lib/security/cacerts -> /etc/pki/java/cacerts
# java 11
ls -l /usr/lib/jvm/jdk-11.0.2/lib/security/cacerts
lrwxrwxrwx 1 root root 21 Oct 29 21:22 /usr/lib/jvm/jdk-11.0.2/lib/security/cacerts -> /etc/pki/java/cacerts

调查了几天，但我没有得到任何结果。我认为这可能是由于版本1.8和11.0之间的SunJSSE安全Provider的变化引起的，但我无法确认。

我不熟悉 java 安全性，想寻求帮助。该示例已简化为该项目，有关重现此问题的说明在 README.md

注意： 该项目是用netty建立的，SSL上下文是使用netty的SslContext建立的。我也尝试使用javax.net.ssl.SSLContext：

SSLEngine engine = SSLContext.getDefault().createSSLEngine();
engine.setUseClientMode(true);

这会导致相同的异常和调用堆栈。

我用 Java 调试运行了您的 docker 映像 (-Djavax.net.debug=all) 并找到了以下内容。 此 Github 问题可能会帮助您找到解决方案。

如果我记得的话，我们在从 JAVA11 迁移到 JAVA8 时遇到了类似的问题，作为将/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.172-9.b11.fc28.x86_64/jre/lib/security/cacerts的内容复制到$JAVA_HOME/jre/lib/security/cacerts解决问题的解决方法。
