The process method would add the StoreBuilders to the topology using builder.addStateStore() and connect the store to that processor, rather than requiring the user to do it themselves.  In order to solve the problem of addStateStore potentially being called twice for the same store (because more than one Supplier specifies it), the check for duplicate stores in addStateStores will be relaxed to allow for duplicates if the same StoreBuilder instance for the same store namename (compared by referenced, not equals() ).
