HTTP/3 in Java - Inside Java Newscast #96
2025-08-01 15:00:03
JEP 517 proposes to update Java’s HTTP Client (introduced in Java 11) to be compatible with HTTP/3. It has lower latency, loads more quickly, and leads to less network congestion and is currently used by about one third of all websites. The API change is minimal with almost all the work happening below the surface. This change opens the door to a lot of future improvements.

How Can Machine Learning Assist to Improve JVM Performance
2025-03-10 14:00:02
Many developers are either unaware of or prefer not to use JVM flags when running their Java applications, especially those requiring complex numerical inputs, such as memory-related flags. Despite the abundance of these flags, tuning even just one or two can significantly enhance application performance, which is critical in performance-sensitive scenarios.

Java 24 - Better Language, Better APIs, Better Runtime
2025-03-01 14:00:03
Java 21 was an explosive release, but 22 to 24 are no slouches either: from unnamed patterns to module imports, from the foreign-function and memory API to stream gatherers and the class-file API, from a simpler main to launching multi-source-file programs, from Markdown in JavaDoc to improved garbage collection. There are plenty of features in the language, API, and runtime to discuss - whether new, improved, or finalized. So let’s go over them!

Valhalla - Java’s Epic Refactor
2024-12-20 14:00:02
Project Valhalla wants to heal the rift in Java’s type system between classes and primitives by introducing value classes, which “code like a class, work like an int” and offer a flat and dense memory layout.
Java’s epic refactor, as it has been dubbed, has been going on for 10 years but is now entering the home stretch.
During Devoxx 2024, Java Language Architect Brian Goetz gave a complete update and explained the proposed solution: value classes, null-restricted types, beefed up definite assignment analysis, and strict initialization.
