Concurrent Garbage collectors: ZGC & Shenandoah

Java 11/12 introduced two new Garbage Collectors: ZGC and Shenandoah. The main objective of these two new GCs is to reduce GC pauses to only few milliseconds (and possibly under a millisecond), therefore solving once and for all the GC problem.

This session will present these two new GCs, how to use them, how to configure them, how they work and an initial discussion on their performances.
