Mateusz Uzdowski ae5bd7d65e ENHANCEMENT: refer to cache statics explicitly via DataObject (os6175)
Unify the usage across the class. Since the intention is to have a
single site-wide cache, calling via DataObject seems to be a better
option - self could theoretically end up calling a redefined field from
a subclass.
