RFR: 8146918: ConcurrentModificationException in MediaPlayer [v2]

[n-gabe]

> There is a ConcurrentModificationException in MediaPlayer when removing a MediaView from it. The root cause is that you can't iterate over a HashSet with for (WeakReference<MediaView> vref : viewRefs) and removing items from the collection by viewRefs.remove(vref); within this loop.
