Keith Wall updated QPID-5834:
-----------------------------
Summary: Trying to delete a default virtual host leaves model in
inconsistent state (was: Trying to deleting a default virtual host leaves
model in inconsistent state)
> Trying to delete a default virtual host leaves model in inconsistent state
> --------------------------------------------------------------------------
>
> Key: QPID-5834
> URL: https://issues.apache.org/jira/browse/QPID-5834
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: 0.29
> Reporter: Keith Wall
> Assignee: Alex Rudyy
>
> If I try to delete the default virtual host, I expect the system to prevent
> the delete from happening and the object remain in its current state.
> At the moment, the model gets into an inconsistent state.
> I see an exception in the logs, and through the UI I see the VH in state
> DELETED but still attached to the VHN. It is as if the delete operation is
> 'half done'.

> We have validation in the doDelete state change method which throws a IVE,
> but the state machinery provided by ACO still lets the state change happen
> regardless.
> State change methods need a mechanism to veto a state change.
