fix at commit time.
# Reword to "it checks whether the application already exists"?
{code}
* <p>During the submission process, it checks whether the application
* has already exist. If the application exists, it will simply return
* SubmitApplicationResponse</p>
{code}
> Mark appropriate protocol methods with the idempotent annotation or
> AtMostOnce annotation
