Your Java application is running smoothly, blissfully unaware of the danger lurking just around the corner. Then—without warning—it vanishes without a trace. Upon investigation, you discover the virtual remains of countless slain JVMs, each marked with the same cryptic number: 137. A serial killer is on the loose in your cluster.
This true crime investigation will walk you through the differences between JVM memory areas, the mechanics of container OOMKills, analysing Grafana dashboards for memory and thread anomalies, interpreting heap dumps, and utilising JVM Native Memory Tracking (NMT) to uncover hidden native memory consumption.
You’ll master practical forensic techniques and proven prevention strategies—from memory tuning tactics and balancing heap vs. non-heap allocations to leveraging large language models (LLMs) for advanced forensic analysis. These skills will help ensure your applications stay alive—even when something’s out to get them.
Just like in a real murder mystery, we may not know whodunnit... but with Martijn Dashorst leading the investigation, you're sure to get closer to the truth.

Staying up to date with Modern Java can feel overwhelming. If you don’t have any experience with recent Java versions (or at all), features like Structured Concurrency or Stream Gatherers might sound exciting, but also scary: “How do I even get started with that?”
Fear not! In this session Marit and Piotr will explain to you the new exciting things and also show you how to use them in your IDE, so that the next day you can start having fun and profit with modern Java in your favorite tools on your own.")
