Replace the line before the return with 

model.addAttribute("listOfMyFriends", listOfMyFriends);

When you do a model.addAllAttributes(listOfMyFriends);

It Copies all attributes in the supplied Collection into this Map, using attribute name generation for each element.

Attribute name generation is done using the method : Conventions.getVariableName()

So, if you are not certain what will be the generated attribute name, use 

 model.addAttribute("listOfMyFriends", listOfMyFriends);

So that you can access the list of your friends using the key "listOfMyFriends"

Add listOfMyFriends to the Model as follows :

model.addObject("listOfMyFriends ", listOfMyFriends );
