"Why this one?" his apprentice had asked earlier that day. "Why not the newest version? Why not a containerized Linux build?"
– The .exe handles file associations ( .jar files) and console integration cleanly, avoiding common path length issues on Windows. jdk17windowsx64binexe better

| Garbage Collector | How to Enable | Strengths | Use Case | | :--- | :--- | :--- | :--- | | | -XX:+UseG1GC (or omit) | Balanced throughput and latency. Pauses are predictable (typically around 200ms). | General-purpose, web servers, microservices, applications with a mix of short-lived and long-lived objects. | | ZGC | -XX:+UseZGC | Ultra-low pause times (consistently below 10ms), even for massive heaps (up to 16TB). | Low-latency, high-performance applications like financial trading systems, real-time analytics, large in-memory caches. ZGC is production-ready in JDK 17. It does use more CPU than G1GC. | | Parallel GC | -XX:+UseParallelGC | Maximizes application throughput. This collector is all about doing work, not about low pauses. | Batch processing, scientific computing, applications where a few long pauses are acceptable in exchange for maximum overall work. | Here is how you can use this installer
The java.exe launcher (and the ProcessHandle API) now respects . If your Java app spawns child processes, the OS can enforce memory/CPU limits globally. This is a game-changer for Windows container scenarios (LCOW) and sandboxed CI runners.
