JEP 546, Adaptive Heap Sizing for ZGC, is now a Candidate! ZGC will adapt heap size to application demand and available host CPU/memory—reducing manual tuning while balancing throughput, latency, GC CPU, and neighboring workloads. openjdk.org/jeps/546

JEP 545, Faster Startup and Warmup with ZGC, is now a Candidate! Complementing Leyden AOT, ZGC reduces the trade-off between fast startup with a small initial heap and smoother performance with a large, pre-touched heap😀

JEP 544 is now Candidate! A major milestone for Project Leyden and the C2 JIT compiler, it speeds startup and warmup by moving compilation into a training run while preserving C2’s dynamic optimization and peak performance 🙂

I would add “Integrity by Default” to that wonderful list as well. It reflects a deliberate move toward a safer, more reliable Java platform—one in which strong encapsulation and secure defaults are the norm, especially for the age of GenAI :-)

Java GC trades heap space for lower CPU overhead: more headroom usually means fewer collections, while less headroom saves RAM but can increase CPU use. Java memory use should not be judged by RAM consumption alone :-)

LLM choice matters, but agentic harness often matters more for enterprise performance, reliability, and cost. LangChain4j gives teams control over context, tools, memory, efficiency, and observability to build production-ready agents. linkedin.com/pulse/you-picke…

JEP 401 brings value classes preview to JDK 28. They enable flattening and scalarization, but are not magic: immutability helps, while megamorphic calls may reintroduce allocation. A great look at how C2 JIT compiler is improving :-)

Functional programming in Java is not about changing Java; it is about expressing intent with concise, composable code. Immutability and pure functions reduce ambiguity, improve verification, and make code easier for LLMs to generate, review and evolve :-)

The JVM offers a unique two-pronged GC performance strategy: use Generational ZGC when protecting p99.9 latency, large heap scaling or use G1 when balanced, high throughput is the goal. Continued C2 compiler and runtime improvements raise peak performance!

An exhaustive switch over a sealed type lets the compiler verify assumptions. Add a permitted subtype and recompilation exposes the missing case. That feedback is a feature: good APIs make tomorrow’s change visible :-)

JDK Flight Recorder (JFR) is embedded in the JVM runtime to capture JVM data with minimal production overhead. It provides historical context —like a JVM time machine—making it a powerful tool for diagnosing real-world production incidents.
