Preference of expiry property at the wildcard destination level and for the specific destination

All

If you specify the expire property at a wildcard destination and then set the expiry property for a specific queue (which is a part of a wildcard destination), the expiry property of the latter would override the property that was set at the wildcard destination level.

For eg:

1. Create a queue "expire" with no expiration set initially.
2. Set the expiration on the queue ">" of 1 day.
3. Do show queue "expire" and check expiration set to 1 day due to inheritance set as per step 2.
4. Now add the expiration on the queue "expire" explicitly of 1 min and after doing show queue "expire" you'll see that the expiration would be overwritten from 1 day to 1 min.
5. Again If you change the expiration of the queue ">" from 1 day to 10 mins to check if the step 4 holds good.
6. Then if you see the properties of the queue "expire", it would still be having expiration set to 1 min as per step 4.
