Azul Systems (who today are mainly a JVM vendor) started by building large multicore boxes (Vega) to do Java workloads - there is an interesting tech talk about it:

They built a "really good JIT target" rather than direct bytecode for reasons explained in the video. Curious to hear from anyone who ever used one...

Yes, was part of Team which used Azul Zing and had very minimal issues.The Primary use-case was to minimize the application downtime during Stop-the-World GC and Zing is almost pause-free.

I wonder how it compares to Shenandoah 2.0, which has been spectacular for me.
