Description

VisibilityController returns false instead of the newValue for the preBalanceSwitch() call.

VisibilityController extends both RegionObserver and MasterObserver, unfortunately only 1 of the two can use the Base implementation. in this case the BaseRegionObserver is used and all most of the MasterObserver methods are a noop. Any idea on how to avoid reimplementing all the interface methods as noop, and avoid problems like the preBalanceSwitch()?
