Reading List ::: from JavaSpecialists
Issue 325 - Be a Distinguished Java Engineer in the Age of Vibe Coding
We are all amazed how AI can help us in everyday tasks. It can even write Java code. But "Show me the Pull Requests" (Evans) sums it up nicely. We do not (yet) see AI massively improving open source projects.Issue 324 - Sequenced LinkedHashSet
LinkedHashSet implements the SequencedCollection interface, allowing us to addLast(), addFirst() and even reverse the collection. This sometimes causes some surprises.Issue 323 - Visiting All Threads (Including Virtual)
In this newsletter, we explore how we can visit the entire hierarchy of threads in our virtual machine, including virtual threads. We do this using the composite, visitor and facade design patterns.Issue 322 - Throwing InterruptedException Early
The LinkedBlockingQueue and LinkedBlockingDeque behave slightly differently when methods put() and take() are called by a thread that happens to be in the "interrupted" state. The LBQ throws an InterruptedException immediately when we call take(), even if the queue contains elements. The LBD, however, only throws InterruptedException if the deque is empty and the thread would enter the WAITING state. In this newsletter we show how a dynamic proxy can make the behaviour consistent.Issue 321 - StampedLock ReadWriteLock Dangers
ReentrantReadWriteLock has a limit of 65536 concurrent read locks. That is an unattainable number with platform threads, but definitely achievable with virtual threads. In this newsletter we explore some of the issues if we want to switch to the StampedLock.asReadWriteLock() instead.Comment Wall

Biome, the all-in-one JavaScript toolchain, has released v2.0 Beta. Biome 2.0 Beta introduces a number of new features in this beta which bring it closer to ESLint and Prettier, such as plugins, to write custom lint rules, domains to group your lint rules by technology and improved sorting capabilities.
By Daniel CurtisArticle: Beyond Objects and Functions: Exploring Data-Oriented Programming
Data-oriented programming (DOP) focuses on how data flows through memory, optimizing layout, cache use, and access patterns. Unlike OOP, DOP boosts performance by reducing cache misses and improving CPU efficiency. It’s ideal for real-time systems like games and trading, often using ECS for parallelism. DOP complements OOP/FP, offering speed and scalability where performance is critical.
