>             Project: jUDDI
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 3.0.4
>            Reporter: Kurt T Stam

> The normal notification process is below:
> 1. Setup a executing time, we assume it's 1:00:10 .
> 2. Get the last notification time of the subscription, we assume it's 1:00:05.
> 3. Get all change services between 1:00:05 -- 1:00:10.
> 4. Notify these change services to client of this subscription.
> 5. If it's success, set the subscription's last notification time to be 'current time'.
> The problem is the step 5, the last notification is updated to be
> 'current time', not the 'executing time', but in step 2, juddi use the
> 'executing time' to be the end time of changed services.
> In some probability, the 'current time' is after 'executing time', then
> when next time notifying, the 'current time' will be used as start time
> at step 2,  all changed services between 'current time' and 'executing
> time' will be lost to notify.
> I changed the code in step 5, set the subscription's last notification
> time to be 'executing time' instead of 'current time', so this issue
> should not happened.
