Dynamic Constants — oxymoron or promising JVM feature?

Day 4 /  / Track 2  /  RU / Hardcore. Really hard and demanding talk, you'll understand only if you're an experienced engineer.

Dynamic Class-File Constants was a feature first introduced in Java 11. But what means dynamic constant? This talk will provide an overview of how the JVM works and why Condy is such a powerful addition. We will also see how little holes in implementation of Condy were causing JVM crash in OpenJ9 and OpenJDK 11-14.

Program committee comment

Highly interesting deep-dive session about a new, "not so well known" VM feature which has the potential of becoming the base for many optimizations in the future.
