queue.yaml not working in App engine (development)

Question

I'm trying to use "queue.yaml" to define queues in a Google App Engine app (Java version).

 queue:
 - name: default
   rate: 5/s
 - name: availableTicketsAlert
   rate: 5/s
 - name: billingReminder
   rate: 5/s
 - name: cseIndexing
   mode: pull

When I try to see if they've been created correctly in this URL: /_ah/admin/taskqueue, I only see "default" queue.

Instead, If I try to create the using with the XML file all works correctly (queue.xml):

<queue-entries>
<queue>
    <name>default</name>
    <rate>5/s</rate>
</queue>
<queue>
    <name>availableTicketsAlert</name>
    <rate>5/s</rate>
</queue>
<queue>
    <name>billingReminder</name>
    <rate>5/s</rate>
</queue>
</queue-entries>

Any ideas of what I'm doing wrong?

Do I have to update them manually with: appcfg.py update_queues myapp/ or something like that?

Thanks!
