En return null if the components isn't available 

  Component _getComponent(Entity e, ComponentType type) {
    int index = type.id;
    Bag<Component> components = _componentsByType[index];
    if(components != null && components.isIndexWithinBounds(e.id)) { //<-- checkIndex
      return components[e.id];
    }
    return null;

Good catch. You're really going into detail ;)
