We have known this was coming for many months now - why is anyone surprised?
The support will revert to JVM vendors where it belongs.
Personally I think it is a good thing - we will get JVM versions much faster than Apple supplied them.
That said, I think that it sure would be nice if my OS already came with Java. But I use Java every day, so maybe I'm biased.
For those of you who are worried about Apple needing to spend a few of the billions of dollars it has in the bank on paying a couple engineers to maintain security patches, it doesn't have to be the Apple or Oracle one either. OpenJDK would be fine.
I'm a bigger fan of having Oracle deal with the porting since they have a much larger interest in getting java working everywhere well and securely than Apple has in keeping java working on their platform.
