JDK 28 advances AOT compilation and ZGC startup and heap features, while GraalVM, Gradle, Quarkus, Micronaut, Maven, Micrometer, Open Liberty, and Hibernate ORM receive multiple releases.
ZGC improvements continue until big users adapt
JEP 546 shows adaptive heap sizing, JEP 545 is about faster startup and warmup with ZGC. Good to see so many ongoing improvements.

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 546: Adaptive Heap Sizing for ZGC
Enhance the Z Garbage Collector (ZGC) to adaptively adjust the size of the heap based on the resources available, the application's needs, and the needs of neighboring applications contending for the same resources.

Do you trade off startup and warmup by tuning -Xms, -Xmx and -XX:+AlwaysPreTouch appropriately? And did you set -XX:+UseTransparentHugePages together with the appropriate shmem_enabled kernel config? Me neither. ”JEP 545: Faster Startup and Warmup with ZGC” is candidate now: openjdk.org/jeps/545
JEP 545: Faster Startup and Warmup with ZGC
Improve application startup and warmup by enhancing the Z Garbage Collector to acquire and prepare physical memory more swiftly and efficiently in response to application needs.

If you are like me and don’t enjoy configuring JVM heap sizes (e.g. -Xms, -Xmx, -XX:SoftMaxHeapSize) then finally ”JEP 546: Adaptive Heap Sizing for ZGC” just became a candidate JEP: openjdk.org/jeps/546

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

AIが脆弱性を見つける時代、セキュリティパッチは3ヶ月も待てなくなったらしい。オラクル、Javaのパッチを毎月配信にするとか。理由が一番時代を感じる。ついでにJava 27はG1 GCが全環境デフォルト。ZGCにばかり目が行くけど、足元を支えてるのはG1だよな。#Java27

Java has Garbage Collection, but it doesn't fix every memory problem. 😄
GC checks whether objects are still reachable. If not, they become eligible for collection.
I explained Heap, GC Roots, G1, ZGC & memory leaks.

I recently visited the messy and experimental Game Builder Garage projects since some Switch 2 updates rolled out!
They're a mess but unironically I think making them helped me figure out gamedev stuff somewhat :D
