How to call operations on JMS temporary queue from JBOSS CLI

I am trying to call operations such as listDeliveringMessages() on a temporary Queue (say fe517553-6c53-42d6-8aaa-d8ea154fd8b0), created by a jms.Topic in JBoss 6.4.0.GA EAP / 7.2.x. I need to do that from JBoss CLI.

I got close to do that by running:

/subsystem=messaging/hornetq-server=default/jms-queue=fe517553-6c53-42d6-8aaa-d8ea154fd8b0

But the JBoss CLI says that the queue is not found. Yet, If i approach this from JVisualVM and check the MBeans, I can run the operations visually (which is not what I am looking for!):

queue

And when selecting that I can have a list of all attributes:

enter image description here

What command should I run to get the same attributes and call operations from JBoss CLI?

Queues used for topic subscriptions can be found in runtime-queue. For example, if you created a subscriber on a topic called myTopic you could run this command:

/subsystem=messaging/hornetq-server=default/jms-topic=myTopic/:list-all-subscriptions

That would give you information on all the current subscribers including the name of the subscription queue, e.g.:

{
    "outcome" => "success",
    "result" => [{
        "durable" => false,
        "queueName" => "6257c1d9-9039-4e76-a4cd-857de77f13a8",
        "messageCount" => 0,
        "deliveringCount" => 0,
        "consumers" => [{
            "creationTime" => 1535727397857L,
            "consumerID" => 0,
            "browseOnly" => false,
            "connectionID" => "397639080",
            "sessionID" => "0fb5712d-ad2e-11e8-94a8-45dabcb25ee3"
        }]
    }]
}

Then you can take the name of the subscription queue and look it up with a command like the following:

/subsystem=messaging/hornetq-server=default/runtime-queue=6257c1d9-9039-4e76-a4cd-857de77f13a8:read-resource(include-runtime=true)

That would tell you all the properties of the queue, e.g.:

{
    "outcome" => "success",
    "result" => {
        "consumer-count" => 1,
        "dead-letter-address" => "jms.queue.DLQ",
        "delivering-count" => 0,
        "durable" => false,
        "expiry-address" => "jms.queue.ExpiryQueue",
        "filter" => undefined,
        "id" => 52L,
        "message-count" => 0L,
        "messages-added" => 0L,
        "paused" => false,
        "queue-address" => "jms.topic.myTopic",
        "scheduled-count" => 0L,
        "temporary" => true
    }
}

However, the list-all-delivering-messages operation doesn't appear to be supported for this queue.
