Have a great goal is a very important thing, such as Moon Landing. What is the meaning of this plan? That's the process of achieving this goal, the produce of industry and technology.

Sun is a great company, in the era of C++, they created JVM & HotSpot.

Now, we have Rust, a better tool, let’s remake JVM!

Pay tribute to medical workers at the front! Thank you for your contribution to the fight against the epidemic.

Roadmap

  • Pass test cases in JDK
  • Pass TCK
  • GC (crate)
  • JIT / interp (crate)
  • class verification (crate)
  • After GC built, ready for optimize System.arraycopy (the key of performance)
  • WebAssembly, make the JVM work in Browser
  • java options (-version, -server...)

In summary, the roadmap is built on a 3-step progress.

  • Pass TCK
  • Refactor & Rewrite
  • Divide into several crates, build a collection of modular and reusable vm technologies

Well, it's a long term plan, Sun spent 30 years to improve VM, Oracle continue doing it.

The journey of a thousand miles begins with one first step. Even the sage was once an ordinary human being.

Just Do It.
