  • How your projects can benefit Graal;
  • How to avoid usual pitfalls using Graal;
  • Lessons learned from Twitter using Graal in production


With JEP 317: Experimental Java-Based JIT Compiler in JDK 10, Graal is now part of OpenJDK. In fact, Graal is already available in JDK 9 due to JEP 243: Java-Level JVM Compiler Interface. Graal is itself written in Java and that brings some new properties and behavior to the table which we haven’t seen with existing HotSpot JIT compilers. This talk will show how to use Graal with JDK 10, how to compile an upstream Graal version and what to look out for when using it for benchmarking or even in production.s
