java Cassandra未启动

Question

我使用的是Windows 10，我已经安装了Cassandra 3.9.0，我更新的JDK版本是java版本“1.8.0_211”

当我运行命令cassandra -f 它不再给我这个错误：

我看过很多帖子，但没有一个能解决我的问题。请建议。如果需要更多信息，请告诉我

见：https://issues.apache.org/jira/browse/CASSANDRA-14173

org.apache.cassandra.utils.JMXServerUtils which is used to programatically configure the JMX server and RMI registry (CASSANDRA-2967, CASSANDRA-10091) depends on some JDK internal classes/interfaces. A change to one of these, introduced in Oracle JDK 1.8.0_162 is incompatible, which means we cannot build using that JDK version. Upgrading the JVM on a node running 3.6+ will result in Cassandra being unable to start.

升级到更新版本的Cassandra（到目前为止为3.11.4）或先降级jdk，问题就会得到解决
