Code review comment: But that enum constant I don't see!

Code under review:
public FeatureFlags(FlagSource source, ApplicationId appId) {
            this.defaultTermwiseLimit = flagValue(source, appId, Flags.DEFAULT_TERM_WISE_LIMIT);
            this.useThreePhaseUpdates = flagValue(source, appId, Flags.USE_THREE_PHASE_UPDATES);
            this.feedSequencer = flagValue(source, appId, Flags.FEED_SEQUENCER_TYPE);
            this.responseSequencer = flagValue(source, appId, Flags.RESPONSE_SEQUENCER_TYPE);
            this.numResponseThreads = flagValue(source, appId, Flags.RESPONSE_NUM_THREADS);
            this.skipCommunicationManagerThread = flagValue(source, appId, Flags.SKIP_COMMUNICATIONMANAGER_THREAD);
            this.skipMbusRequestThread = flagValue(source, appId, Flags.SKIP_MBUS_REQUEST_THREAD);
            this.skipMbusReplyThread = flagValue(source, appId, Flags.SKIP_MBUS_REPLY_THREAD);
            this.useAccessControlTlsHandshakeClientAuth = flagValue(source, appId, Flags.USE_ACCESS_CONTROL_CLIENT_AUTHENTICATION);
            this.useAsyncMessageHandlingOnSchedule = flagValue(source, appId, Flags.USE_ASYNC_MESSAGE_HANDLING_ON_SCHEDULE);
            this.feedConcurrency = flagValue(source, appId, Flags.FEED_CONCURRENCY);
            this.reconfigurableZookeeperServer = flagValue(source, appId, Flags.RECONFIGURABLE_ZOOKEEPER_SERVER_FOR_CLUSTER_CONTROLLER);
            this.useBucketExecutorForLidSpaceCompact = flagValue(source, appId, Flags.USE_BUCKET_EXECUTOR_FOR_LID_SPACE_COMPACT);
            this.enableFeedBlockInDistributor = flagValue(source, appId, Flags.ENABLE_FEED_BLOCK_IN_DISTRIBUTOR);
            this.maxDeadBytesRatio = flagValue(source, appId, Flags.MAX_DEAD_BYTES_RATIO);
            this.clusterControllerMaxHeapSizeInMb = flagValue(source, appId, Flags.CLUSTER_CONTROLLER_MAX_HEAP_SIZE_IN_MB);
        }

Line commented on: this.clusterControllerMaxHeapSizeInMb = flagValue(source, appId, Flags.CLUSTER_CONTROLLER_MAX_HEAP_SIZE_IN_MB);
