Code Review Request for Bug #4802647

[Brandon Passanisi]

Here's an updated webrev for review for 4802647, which also contains a 
fix for 7123424.  7123424, as noted below, is the newly filed bug 
regarding the same bug behavior for CopyOnWriteArrayList and 
CopyOnWriteArraySet.  It seems best to combine the fix for both into one 
webrev, so this webrev for review is a reflection of this:

Thanks.
