看你的报错好像是MBeanServer对象或者下面的mbsInterceptor没有获取到。我这边没有tomcat9的环境，你可以尝试在idea中断点，然后在Evaluate执行下面代码看看对象是否存在
MBeanServer对象:
org.apache.tomcat.util.modeler.Registry.getRegistry((Object)null, (Object)null).getMBeanServer();
mbsInterceptor对象：
org.apache.tomcat.util.modeler.Registry.getRegistry((Object)null, (Object)null).getMBeanServer().mbsInterceptor
下面是我在tomcat8.x执行的结果
