tl;dr: IBM is breaking apart its JVM runtime technology to allow easy reuse and integration of its GC, JIT and Tooling into other languages. This has been proven with a JIT + GC + Diagnostics enabled version of Ruby (MRI) and Python (CPython)
Why did you decide to show results from the synthetic benchmarks in bench9000, when there are 43 kernels from real compute-intensive libraries that are in-use in production (the PSD.rb and Chunky PNG benchmarks)?
Working on JRuby+Truffle I found that I could actually better optimise those benchmarks compared to the synthetic ones. The more complex code provides more opportunities to make big gains in performance compared to the simple code in the synthetic benchmarks.
The team is interested in working on a paper, once the hard work is closer to being done.
Open sourcing will happen. Doing it right is very important to us however, so we don't know when.
