Buggy source:
@Override public boolean initGameApp(Handle<GameAppContext> thisContext,Handle<GameAppContext> parentContext,java.util.Map<String,String> additionalParams){
  if (parentContext == null || additionalParams.isEmpty()) {
    return false;
  }
  Map mapEntity=MapJpaController.get().findMap(Integer.parseInt(additionalParams.get("String_Node_Str")));
  boolean isPvP=Boolean.parseBoolean(additionalParams.get("String_Node_Str"));
  int instanceNum=Integer.parseInt(additionalParams.get("String_Node_Str"));
  DistrictRegion region=DistrictRegion.valueOf(additionalParams.get("String_Node_Str"));
  DistrictLanguage language=DistrictLanguage.valueOf(additionalParams.get("String_Node_Str"));
  if (mapEntity == null) {
    return false;
  }
  WorldBean world=new WorldBean(mapEntity,instanceNum,region,language,isPvP);
  EventAggregator eventAgg=thisContext.get().getEventAggregator();
  HandleRegistry<ClientBean> clientRegistry=new HandleRegistryNotificationDecorator<>(eventAgg);
  EntityManager entityManager=new EntityManager();
  thisContext.get().getEventAggregator().register(new ClientConnect(thisContext,parentContext,clientRegistry,world,entityManager)).register(new ClientDisconnect(thisContext,parentContext,entityManager)).register(new ShutDown(thisContext,parentContext)).register(new LatencyAndSynchonization(clientRegistry)).register(new CharacterCreation()).register(new Chat(eventAgg)).register(new InstanceLoad(world,entityManager)).register(new MoveRotateClick(eventAgg)).register(new AgentVisibilitySystem(eventAgg,entityManager)).register(new ChatSystem(eventAgg,clientRegistry)).register(new CommandSystem(eventAgg,entityManager,clientRegistry)).register(new MovementSystem(eventAgg,entityManager,clientRegistry)).register(new SchedulingSystem(eventAgg)).register(new SpawningSystem(eventAgg,clientRegistry));
  return true;
}

Fixed version (ground truth):
@Override public boolean initGameApp(Handle<GameAppContext> thisContext,Handle<GameAppContext> parentContext,java.util.Map<String,String> additionalParams){
  if (parentContext == null || additionalParams.isEmpty()) {
    return false;
  }
  Map mapEntity=MapJpaController.get().findMap(Integer.parseInt(additionalParams.get("String_Node_Str")));
  boolean isPvP=Boolean.parseBoolean(additionalParams.get("String_Node_Str"));
  int instanceNum=Integer.parseInt(additionalParams.get("String_Node_Str"));
  DistrictRegion region=DistrictRegion.valueOf(additionalParams.get("String_Node_Str"));
  DistrictLanguage language=DistrictLanguage.valueOf(additionalParams.get("String_Node_Str"));
  if (mapEntity == null) {
    return false;
  }
  WorldBean world=new WorldBean(mapEntity,instanceNum,region,language,isPvP);
  EventAggregator eventAgg=thisContext.get().getEventAggregator();
  HandleRegistry<ClientBean> clientRegistry=new HandleRegistryNotificationDecorator<>(eventAgg);
  EntityManager entityManager=new EntityManager();
  thisContext.get().getEventAggregator().register(new ClientConnect(thisContext,parentContext,clientRegistry,world)).register(new ClientDisconnect(thisContext,parentContext,entityManager)).register(new ShutDown(thisContext,parentContext)).register(new LatencyAndSynchonization(clientRegistry)).register(new CharacterCreation()).register(new Chat(eventAgg)).register(new InstanceLoad(world,entityManager)).register(new MoveRotateClick(eventAgg)).register(new AgentVisibilitySystem(eventAgg,entityManager)).register(new ChatSystem(eventAgg,clientRegistry)).register(new CommandSystem(eventAgg,entityManager,clientRegistry)).register(new MovementSystem(eventAgg,entityManager,clientRegistry)).register(new SchedulingSystem(eventAgg)).register(new SpawningSystem(eventAgg,clientRegistry));
  return true;
