> Currently, the ApplicationImpl receives an INIT_APPLICATION event on every
> container initialization. Only on the first one does it really mean to init
> the application, whereas all subsequent events are for specific containers.
> This JIRA is to separate the events into INIT_APPLICATION, sent once and only
> once per application, and INIT_CONTAINER, which is sent for every container.
> The first container sends INIT_APPLICATION followed by INIT_CONTAINER.
