Abstract

Deep dive into the backport — Rémi Forax

This talk will present the JSR 292 backport that implement JSR 292 specification on 1.5, 1.6 compatible Java Platforms.

After a short intro about the JSR292, the backport roadmap and bytecode weaving. I will talk about the first design of the backport and why it fails. Next, I will introduce the new design (the one currently implemented) how it works and how it optimizes method handle adapters that are some not so easy to optimize for a bytecode weaver.

I will finish by showing some benchmarks that will highlight how the optimizer works and some comparison graphs between the JSR292 Reference Implementation and the backport.
