Any plans to support native-image?

1. com.github.benmanes.caffeine.cache.NodeFactory.newFactory(Caffeine<K, V> builder, boolean isAsync); uses reflection.

That should be compatible, it simply requires including the required classes in the reflection configuration. Graal, Micronaut, Spring seem to support native image with caffeine. When I asked them if we should do anything, I was told that was the framework’s responsibility to maintain. I guess look at what they did as a reference.

The application of springboot3 provides RuntimeHintsRegistrar to register classes that need reflection.

[wangliang181230]

class TestRuntimeHints implements RuntimeHintsRegistrar {

    @Override
    public void registerHints(RuntimeHints hints, @Nullable ClassLoader classLoader) {
        ReflectionHints reflectionHints = hints.reflection();
        reflectionHints.registerType(clazz, INTROSPECT_DECLARED_CONSTRUCTORS, INVOKE_DECLARED_CONSTRUCTORS);
    }

}

org.springframework.aot.hint.RuntimeHintsRegistrar= \
xxx.TestClientRuntimeHints

fyi, you might want to conditionally include the Caffeine classes that are specific to the configuration. We codegen the entry types to minimize memory overhead, which was a good strategy pre-AOT because unloaded classes are free. If instead included in an AOT build then this will add significant bloat (see quarkusio/quarkus#12961).

When I register all of the Caffeine classes, the size of the exe file, as well as the memory, has only increased by about 1.5M ~ 2.5M, not 14M.

However, I also think that less registration is better. I will only register the classes used.
Thank you.
