Questions on AuxiliaryService

HI all,


I found that the AuxiliaryService's implementation is a little confusing to
me. The initializeApplication will be invoked on each container of one
application including the am. While stopApplication will only
been invoked on am when the job is done. It looks like there's a little
mismatch between these 2 methods, could anyone explain to me why design it
like this ? Thanks
