> The {{SchedulerHealth}} class has some flaws, for example:
> - It has no javadoc at all
> - All its objects are package-private: they should be private
> - The internal maps should be (Concurrent) EnumMaps instead of HashMaps: they are more efficient in storing Enums
> - schedulerHealthDetails only stores the last operation, its name should reflect that (just like lastSchedulerRunDetails)
