Description

The following allocation file

<?xml version="1.0"?>
<allocations>
<queue name="root">
  <aclAdministerApps>someuser </aclAdministerApps>
  <queue name="default">
    <aclAdministerApps>someuser </aclAdministerApps>
  </queue>
  <queue name="dedicated">
    <reservation>
    </reservation>
    <aclAdministerApps>someuser </aclAdministerApps>
  </queue>
</queue>
<defaultQueueSchedulingPolicy>drf</defaultQueueSchedulingPolicy>
</allocations>

is being parsed as: PARENT=[root, root.dedicated], LEAF=[root.default, root.dedicated] (AllocationConfiguration.configuredQueues).

The root.dedicated should only appear as a PARENT queue.
