It's a lot of work, and I don't know that there's any support for the effort to port V8 and ART to RISC-V. When I was starting on V8 port, I didn't see much in terms of interest in providing material support for it.
I got one interview out of it, but I feel like maybe the Foundation is the right place for that. They'd have to delegate the hiring and management to a member, but I think it could work.
Huawei has their own VM for Android, so they would likely port that for their effort.
Absolutely, giants like Google or Huawei could pull this off, I really don't know if we'll see Java without someone like that. Personally I'm keen to see Mozilla's JavaScript VM (is it still called SpikerMonkey?) ported, but I doubt it will happen until we see more widely available/affordable RISC-V hardware.
I just don't have any interest in running any software that uses mozilla's JavaScript runtime. It has a lot going for it but I just find Mozilla based browsers misbehave and perform poorly on all my hardware, in ways that upset and frustrate me.
