Description
If a management-context connector is configured in management.xml (e.g. below) and org.apache.activemq.artemis.core.server.impl.ActiveMQServerImpl#stop(boolean, boolean, boolean) is called (e.g. due to criticalIOErrors) the JVM will not exit due to a handful of leaked RMI related threads for the MBean server implementation.
<management-context xmlns="http://activemq.org/schema"> <connector connector-port="1099" connector-host="0.0.0.0"/> ... </management-context>
Here's an example thread dump after the broker has stopped:
