JDK 26 comes with JEP 526, which previews `LazyConstant`, a type that lazily initializes a value through a given `Supplier`. It executes that supplier at most once successfully and then assigns the value to a field annotated with `@Stable`, which allows constant folding. This API is also a poster child for how OpenJDK develops and evolves features.
