Fixed version (ground truth):

  String childId=statusEvent.getId();
  String instanceId=statusEvent.getInstanceId();
  LifeCycleState status1=statusEvent.getStatus();
  if (status1 == ClusterStatus.Active || status1 == GroupStatus.Active) {
    onChildActivatedEvent(childId,instanceId);
  }
 else   if (status1 == ClusterStatus.Inactive || status1 == GroupStatus.Inactive) {
    this.markInstanceAsInactive(childId,instanceId);
    onChildInactiveEvent(childId,instanceId);
  }
 else   if (status1 == ClusterStatus.Terminating || status1 == GroupStatus.Terminating) {
    markInstanceAsTerminating(childId,instanceId);
  }
 else   if (status1 == ClusterStatus.Terminated || status1 == GroupStatus.Terminated) {
    removeInstanceFromFromInactiveMap(childId,instanceId);
    removeInstanceFromFromTerminatingMap(childId,instanceId);
    ApplicationInstance instance=(ApplicationInstance)instanceIdToInstanceMap.get(instanceId);
    if (instance != null) {
      if (isTerminating() || instance.getStatus() == ApplicationStatus.Terminating || instance.getStatus() == ApplicationStatus.Terminated) {
        ServiceReferenceHolder.getInstance().getGroupStatusProcessorChain().process(this.id,appId,instanceId);
      }
 else {
        Monitor monitor=this.getMonitor(childId);
        boolean active=false;
        if (monitor instanceof GroupMonitor) {
          active=verifyGroupStatus(childId,instanceId,GroupStatus.Active);
        }
        if (!active) {
