Seems like the contructor for StateHolderSaver is not null safe?
I got a NullPointerException in a table when the state should be saved.

1. Location in code where the constructors i called - UIComponentBase, method saveAttachedState, row 1175```
   ...
   resultList.add(new StateHolderSaver(context, value));
   ...

2. In my case the 'value' above is null so that StateHolderSaver constructor will then throw a NullPointerException since the code invokes toSave.getClass().getName(). Se below:```
   ....
   public StateHolderSaver(FacesContext context, Object toSave) {
   this.className = toSave.getClass().getName();
   ....
   }

• This must be a very common use case (that a 'value' is null to be persisted/restored). Is it my code that´s using the StateHolderSaver in a special way or is this a new bug in 2.1.12?
