Hello! I have some news about this bug. 
Sometimes i've been got NullPointerException at Tween.java line 22: 

@Override public void onUnPool(Tween obj) {obj.reset();}

As I understand onUnPool() was called from Pool.java (line 22)

if (callback != null) callback.onUnPool(obj);

which is similar to issue that I've been described early. Hope it will help to 
solve this problem.

+1 for this. I am getting the same two exceptions repeatedly in my latest app 
on Google Play, and would like to know if anyone is working on it.
Thank you!

I've got at aurelienribon.tweenengine.Tween.to(Tween.java:208) too. It happens 
very often. Please fix it.
