This presentation was recorded at GOTO Copenhagen 2023. #GOTOcon #gotocph Evgeny Mandrikov - Software Gardener, Language Team Technical Leader at SonarSource @EvgenyMandrikov RESOURCES ABSTRACT New JVM features now arrive with each JDK release. If you are interested to learn and try these new features and wanna know-how in case of problems investigate and report JVM crashes, then come to listen about its new feature introduced in Java 11 - Constant Dynamic. During this talk, we'll see what actually means dynamic constant and why it is such a powerful addition to JVM. We'll also see how little holes in implementation were causing JVM crashes in OpenJ9 and OpenJDK 11-14, and how by developing JaCoCo we find and report such bugs - you also can!
