GraalVM for JDK 25: New Features and Practical Tips

GraalVM is now well recognised as the best way to run Java applications faster, with lower memory overhead, and great startup times. While many organisations have already adopted it, some might still wonder about the best strategies to use it in practice.

In this session, we'll go through strategies for optimising performance and builds, working with libraries and configuration, and deploying production-ready native applications.

We’ll also cover what’s new in GraalVM for JDK 25 (going live in September—stay tuned!) and take a look at some advanced and forward-looking projects, such as:
– ML-based profile inference
– Project Crema
– Native Image Layers
– New `-H:Preserve` mode
