I have a question use runtimeConfigurationPlugins

[??????o.--]

Hi  When i use runtimeConfigurationPlugins on a single broker it works.The 
expected effect has been achieved
When I used the same configuration in ActiveMQ + zookeeper, there was an error. 
And all three nodes exposed port 8161
This is the activemq.log
WARN || org.eclipse.jetty.servlet.ServletHandler |qtp749115872-17
