☕ Java 26 — JEP 516: Ahead-of-time object caching with any GC

· java

# Example JVM launch using a GC that now works with AOT object caching

java -XX:+UseZGC -XX:+AOTStreamableObjects -jar app.jar

• This is Project Leyden work aimed at improving startup and warmup.

• The important change in JDK 26 is that ahead-of-time object caching is no longer tied to a specific garbage collector.

• That means more applications, including ones using ZGC, can benefit from faster cold starts.
