Symptom:
An application crashed due to IndexOutOfBoundsException.
The exception was thrown at WindowManagerGlobal#setStoppedState.
Root cause:
setStoppedState invokes setWindowStopped for each ViewRoot by
ascending order. If an application removes its view within the
loop, loop index exceeds the number of items.
Solution:
Loop in descending order.
