>> By annotating `SharedSecrets` as `@AOTSafeClassInitializer`, we can avoid using the `@AOTRuntimeSetup` annotations in a few JDK core classes. This simplifies the implementation. It also brings us closer to the goal of making the AOT cache as a true snapshot of the JVM state that just needs to be resumed in the production run.
