JEP 401, integrated into JDK 28, introduces value objects. These new class instances feature final fields, altered behavior for equality checks, and stricter construction and synchronization rules. It aims to enhance efficiency and reduce memory allocation costs. However, the preview is disabled by default and requires specific configuration at compile and run time.

This week's Java roundup for August 3rd, 2026, features news highlighting: JEP 535, Shenandoah GC: Generational Mode by Default, targeted for JDK 28; point releases of A2A Java SDK, Apache Camel and Gradle; a maintenance release of GlassFish; the fifth milestone release of Groovy 8.0; and a follow-up of the JetBrains TeamCity CVE.

Laurence Tratt discusses yk, an open-source meta-tracing JIT compiler framework. He shares how to automatically speed up C-based language interpreters like Lua and MicroPython with minimal, non-invasive code changes. He explains the inner workings of tracing loops, optimizing compiled traces using developer hints, and managing complex deoptimization back to the interpreter.
