    Description

      If there is no new events greater than the requested event, ObjectStore.getNextNotification will return an empty NotificationEventResponse. And the client side will get the following exception:

       [ERROR - org.apache.thrift.server.TThreadPoolServer$WorkerProcess.run(TThreadPoolServer.java:295)] Thrift error occurred during processing of message.
      org.apache.thrift.protocol.TProtocolException: Required field 'events' is unset! Struct:NotificationEventResponse(events:null)
