Start with JmxConnectorServerFactoryBean and com.alibaba.otter.manager.biz.remote.impl.NodeMBeanServiceImpl at line 76, then reproduce the reported client connection failure using the service:jmx:rmi URL shown in the issue. Trace the server and client endpoints involved in the refused connection; done means the JMX client obtains a connection successfully without the reported exception.
