Here are a few highlights: An explanation for why not to use unit tests for AOT training runs on JDK 24, a garbage collection primer and comparison, two tips on how to analyze your Maven build, the announcement that final will eventually mean really final and how to simulate that today, a detailed look at how to build an advanced retrieval augmenter for quering AI models, and last but not least, the roadmap for value types and null restriction.
