Class AotClassLoadingExamples

java.lang.Object

net.jrodolfo.java_evolution.java24.aot_class_loading.AotClassLoadingExamples

public class AotClassLoadingExamples
extends Object

Demonstrates ahead-of-time class loading and linking, introduced in Java 24.

The example runs the explicit JEP 483 workflow: compile a tiny application, package it as a JAR, record AOT configuration, create an AOT cache, and run the application with that cache. It verifies workflow behavior, not startup speed.
