Почему throws не обрабатывается?

Есть следующий код:

DefaultAnimationComposer.java

public class DefaultAnimationComposer implements AnimationComposer{
    private ArrayList<AnimationAction> animationCollection = new ArrayList<>();
    private volatile boolean  isWorking = true;
    @Override
    public void addAnimation(AnimationAction animation){
        animationCollection.add(animation);
        animation.subscribe(this);
        animation.setDelay();
    }
    @Override
    public void onAnimationEnded(AnimationAction animation){
        try{
            new Handler().postDelayed(() -> animationCollection.get(animationIndex + 1).executeAction(), delay);
        }catch(NullPointerException ex){
            ex.printStackTrace();
            onAnimationEnded(animationCollection.get(animationIndex + 1));
        }
    }
}

SomeClass.java

animationComposer.addAnimation(new AnimationAction(){
                @Override
                public void executeAction() throws NullPointerException{
                        doneView.setAlpha(1f);
                        doneView.setSpeed(0.7f);
                        doneView.playAnimation();
                        Log.d(TESTING_TAG, "executeAction()2 in RegisterFragment");
                        doneView.addAnimatorListener(new ExecuteNextAfterEndListener(animationComposer, this));
                }
                @Override
                public void setDelay(){
                    delay = 100;
                }
            });

При пересоздании экрана doneView становится Null. Соот-но метод setAlpha() должен выбрасывать NullPointerException, а эта ошибка должна обрабатываться в onAnimationEnded() в классе DefaultAnimationComposer, однако этого почему-то не происходит.

UPD:

Обновил код, однако все равно не работает.

animationComposer.addAnimation(new AnimationAction(){
            @Override
            public void executeAction() throws NullPointerException{
                try{
                    doneView.setAlpha(1f);
                    doneView.setSpeed(0.7f);
                    doneView.playAnimation();
                    Log.d(TESTING_TAG, "executeAction()2 in RegisterFragment");
                    doneView.addAnimatorListener(new ExecuteNextAfterEndListener(animationComposer, this));
                }catch(NullPointerException ex){
                    subject.onAnimationEnded(this);
                }
            }
            @Override
            public void setDelay(){
                delay = 100;
            }
        });
