I think you are just observing ArrayList's toString behavior.
BeanUtils.getProperty() returns the same object that the corresponding
getter method returns.
Try replacing System.out.println(map) with something like
System.out.println(map.get("childs").getClass().getName()) to see what
the actual object type is.
