/**
 * This is a disabled implementation of ManagedEntityController for bug #47909.
 *
 * The old ManagedEntityController was a concrete class which has been renamed to
 * ManagedEntityControllerImpl. The build.xml now skips building ManagedEntityControllerImpl. If
 * ManagedEntityControllerImpl is not found in the classpath then the code uses
 * DisabledManagedEntityController as a place holder.
