I know that Shenandoah code was accepted to OpenJDK not so long ago and as far as I know it would be beta on OpenJDK 9. I would like to hear the thoughts you guys have about it. Do you guys think it would be like Azul VM one? Is the throughput of Azul VM so high that worth to buy its license? About G1 GC algorithm, do you think it would also evolve like Shenandoah plan to keep improving or it would be like the other GC algorithms which didn't have major changes?
