I'm definitely pushing for this to be added ASAP — probably won't be before 10 though. In the meantime, it would be awesome if they could get it into OpenJDK behind a flag...
There's no real work being done on this at the moment (I was involved with trying to kick start a small team with the original patch authors). We've started discussing it again, but it's looking like a case of "Real Life" getting in the way :-|. Will see if I can get the broader Adopt OpenJDK programme to take it on board.
