Dissecting the CPU-Memory Relationship in Garbage CollectionThis article analyzes why we need to look beyond GC pauses to enable maximal infrastructure efficiency and introduces the new Java API for GC CPU in OpenJDK 26. These capabilities empower engineers and researchers to quantify the collector's CPU overhead, providing the data necessary to make informed decisions regarding the memory-CPU trade-off.

Serialization has been a part of the Java Platform since the 1.1 release. While serialization brings with it a lot of utility and was key in Java's early success, it does have some pretty significant issues as well. In this episode of Stack Walker, we review the history of serialization, the concerns it was attempting to address, and how some of those design decisions have resulted in more than a few headaches for JDK engineers and Java developers alike. We will then look at how the JDK engineering team is working towards addressing the issues that serialization presents and ultimately a replacement.

In 2026, Java keeps evolving: Project Valhalla is gunning for merging its value types preview in the second half of this year; Babylon wants to incubate code reflection; Loom will probably finalize the structured concurrency API; Leyden plans to ship AOT code compilation; and Amber hopes to present JEPs on constant patterns and pattern assignments. And those are just the most progressed features - more are in the pipeline and discussed in this episode of the Inside Java Newscast.
Read MoreTowards Better Checked Exceptions - Inside Java Newscast #107
Java's checked exceptions are both an integral part of the language and one of its most contested features. Whether their introduction was a mistake and whether they should all be turned unchecked are frequently discussed topics but since the former is not overly relevant and the latter unlikely, this conversation isn't moving Java forward. Instead, let's talk about specific issues with checked exceptions and what could be done about them - from (entirely speculative) language changes to (marginally realistic) JDK/library evolution to stylistic changes.
Read MorePost-Quantum Hybrid Key Exchange for TLS 1.3
JEP 527 is now integrated into JDK 27! This feature enhances the security of Java applications by implementing hybrid key exchange algorithms for TLS 1.3. By combining quantum-resistant ML-KEM with traditional elliptic-curve algorithms, the JDK implementation of TLS 1.3 is protected against 'harvest now, decrypt later' threats.
