[AMQ7, DLA, auto create] DLA addresses do not auto create

When a message is sent to a DLA address that has not been created beforehand, the broker prints out the following message:

~~~

I have confirmed with engineering that the DLA queues are not auto created. When messages are sent from clients, the addresses are auto-created but NOT when messages are sent within the broker even when the 'auto-create-addresses=true' is set.

It would be nice to have the broker auto-create DLA addresses when 'auto-create-addresses=true'
