> This PR adds a new annotation, `@AOTInitialize` that forces a class to be (a) > initialized in the AOT assembly phase, and (b) stored in the AOT cache in an > already initialized state. This means that all the static fields in this > class will be immediately available upon JVM bootstrap when the AOT cache is > used in an application's production run. > > This PR annotates a single class, `jdk.internal.math.MathUtils`. More classes > will be added in future PRs. > > If a class `K` has the `@AOTInitialize` annotation, the same annotation must > be also added to > - All of `K`'s super classes > - All of `K`'s super interfaces that require to be initialized when `K` is > initialized (see JVMS 5.5. Initialization, step 7; also C++ function > `InstanceKlass::interface_needs_clinit_execution_as_super()` > > Note, the check of the above requirement has been moved to > `AOTClassInitializer::check_aot_annotations()`. The previous check in > `ClassFileParser` was not executed because the class is loaded in the AOT > training run, where `CDSConfig::is_initing_classes_at_dump_time()` returns > `false` (this function returns `true` only in the AOT assembly phase). > > This annotation is awfully similar to `@AOTSafeAnnotation`, and I am not sure > if we need both. Please see the javadoc in `@AOTInitialize` to see the > difference between the two annotations.
