VerifyError：向后分支Kafka Win-10上存在未初始化的对象

Question

在本地计算机（Windows 10）中使用以下命令启动Kafka服务器时，我遇到了一个问题

有什么办法解决这个问题吗？

Answer 1

您的java_home环境变量似乎有问题。确保java_home具有JRE(Java运行时环境）的路径，而不是JDK(Java开发工具包）的路径。

为了安全起见，如果不确定它是否真的导致了不兼容，请考虑将1.8.0_241用于Scala支持库。

e.g. my JAVA_HOME environment variable: C:\Program Files\Java\jre1.8.0_241
