JEE Town Reading List ::: from JavaSpecialists

Issue 337 - Module Imports

Module imports are a new feature in Java 25 and are like a wildcard import for *all* the types in a module. If you hate wildcard imports, you'll despise this even more. But if, like me, you don't really care whether someone uses a wildcard or single-type import, this is for you.

Issue 336 - CopyOnWriteArrayList.subList() ConcurrentModificationException

Java's CopyOnWriteArrayList gives us a snapshot iterator for fast reading. However, its subList() is not snapshot, and will break if the list is changed. In this newsletter we look at a way to make a safe subList() copy, using the iterator and an AbstractList.

Issue 335 - ZGC Mysteries

In our previous newsletter we posted a puzzle about ArrayList creation in ZGC. Lots of Java programmers sent in their ideas, and we are still looking for the perfect answer. Here are some more thoughts on the idea, whilst we wait for The Z Garbage Collector Book to arrive.

Presentation: Multi-Agent Patterns from Spotify’s AI Powered Advertising Platform

Pratik Rasam discusses how Spotify Ads Manager runs production-grade multi-agent systems at scale using Google ADK Java. He shares key architectural patterns, domain ownership models, deterministic guardrails, and tracing-based evaluation strategies, detailing hard-learned lessons on drawing agent boundaries, optimizing tool schemas, and managing costs while avoiding monolithic agent pitfalls.

Technological Sovereignty Requires Choice, Skills, and Support, Panelists Say During OSS EU

European organisations can enhance their technological sovereignty by developing credible alternatives and acquiring necessary skills, rather than completely avoiding global providers. A panel discussion at the OSS EU highlighted the importance of understanding dependencies in cloud and hardware, and emphasized the need for practical choices in software for effective operational sovereignty.

Survey Finds AI-Generated Code Increases Debugging and Failure Rates and Creates a Comprehension Gap

A survey conducted by independent research firm Coleman Parkes on behalf of Undo, a company focused on scaling AI-powered root-cause analysis, found that while AI coding agents have accelerated code generation, they have shifted the primary bottleneck to debugging, code comprehension, and maintenance.

The Async Multiprocessing Has Sound Foundations in Linux, But Further Testing Is Needed

At Embedded Linux Conference Europe 2026, Wolfram Sang discussed the Linux building blocks for asymmetric multiprocessing (AMP). He highlighted the solid foundation but noted challenges like limited contributor coverage and fragmented testing. Sang's work on a hardware-spinlock driver revealed maintenance complexities and the need for more reviewers and testers to support evolving AMP systems.
