JobInfo is a structure to represent the status of each single jobs.
It looks strange that it includes the info of whole job list.

Rather than adding it to the field, wouldn't it be possible to obtain the data
by, for instance, calling GetJobInfoList().size() in each listener?
(If it is too inefficient, you can add a new method to get just the number
in JobList class)

Now, EventRouter can not call GetJobInfoList().size(). EventRouter needs to have
the instance of JobScheduler to call it.
