Thanks for doing this.
Though as I suggested last time personally I prefer to make minimum
change to simply
seal those holes in ASB at this late stage of JDK9. I'm fine with the
webrev.2 and it looks
better and reasonable to pull all UTF16 operations into StringUTF16.java.
Just for my curiosity, does the change in String#1810 make difference?
