Without architecture and design, the agent decides everything per feature: where the code goes, how it talks to the rest of the system, which operations to expose, and what the data looks like. Architecture removes…
From time scales to checkpointing, from managing to inspecting cache files, there are a number of details to consider when creating AOT caches for faster Java application launches.
Hi, Spring fans! In this conversation, Spring Tools lead Martin Lippert joins us for a fascinating look at how developer tooling has evolved from Eclipse to VS Code and beyond. We dig into the architecture behind Spring…
BoxLang has always been an extensible language. As of 1.17.0, it is a hierarchically extensible one. Modules can now contain other modules; aka Module Inception. Recursively. To any depth. Each nested module gets its…
Philip Wadler invented a coherent mechanism in 1988. Thirty-one years later, he co-authored a paper trying to get some of that coherence back. Type classes are one of the rare programming language features with a clean…
promotes compact object headers to the default layout in HotSpot. The feature itself is the one we met in JDK 25 as a production option (), having started life as an experimental flag back in JDK 24.

: “Due to late-breaking feedback, the owner of this JEP has decided do one more preview round.” The feedback itself never became public: it is not on security-dev, in the implementation PR or in the CSR. The owner is…
continues the marathon, the seventh preview of Structured Concurrency, following (sixth preview) in JDK 26. The API treats a group of concurrent subtasks as a single unit of work, with unified cancellation and error…

is the kind of change that sounds boring until you realize how many edge cases it quietly eliminates. As would gleefully remind us, the JCP doesn’t technically recognize the concept of a “default garbage collector”, but…
