Not all client connections have a registered ObjectName
-------------------------------------------------------
Key: AMQ-3419
URL: https://issues.apache.org/jira/browse/AMQ-3419
Project: ActiveMQ
Issue Type: Bug
Components: JMX
Affects Versions: 5.6.0
Environment: Linux, OSGI
Reporter: Michael Yara
I am trying to force client disconnects from my embedded ActiveMQ broker via
JMX. I am currently using the latest 5.6 snapshot. In my testing I have found
that not all the client connections have a relative MBean registered.
I ran this test on my BrokerService:
Connection[] clients = brokerService.getBroker().getClients();
for(Connection c : clients) {
System.err.println(c.getConnectionId());
}
Set beans = brokerService.getManagementContext().queryNames(null, null);
for(Object bean : beans) {
if(bean instanceof ObjectName) {
ObjectName name = (ObjectName)bean;
System.err.println(name);
}
}
This is the output:

It seems as if only the last client connection has a NameObject.
