> 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.
