Well, JikesRVM is a proper JIT. Palmer Dabbelt from SiFive has worked on a HotSpot port before (for a different platform). I'm currently working on a V8 port. The availability of platform software and language environments is obviously of paramount importance, since it'll shape the remaining first impressions of the architecture.

Well, it's a lot of work, and they have their SPARC investment to continue.
I am too. So far, this post on the general RISC-V mailing list and a few videos online talk about it. I'd love to have some other sources of information on their progress.
Also, I've heard that the RISC-V foundation is actively seeking collaboration for Java. There is some work on having RISC-V backends in HotSpot and JikesRVM, but so far it is limited to interpretation IIRC. The fact that Oracle is not jumping at it and pouring hundred of millions into it is beyond me.
