public class V2UpdateRequestHandler
extends UpdateRequestHandler

An extension of UpdateRequestHandler used solely to register the v2 /update APIs

At core-load time, Solr looks at each 'plugin' in ImplicitPlugins.json, fetches the v2 Api implementations associated with each RequestHandler, and registers them in an ApiBag. Since UpdateRequestHandler is mentioned multiple times in ImplicitPlugins.json (once for each update API: /update, /update/json, etc.), this would cause the v2 APIs to be registered in duplicate. To avoid this, Solr has this RequestHandler, whose only purpose is to register the v2 APIs that conceptually should be associated with UpdateRequestHandler.
