Stable values are a new API that JEP 502 aims to add to #Java 25. A stable value holds an on-demand at-most-once computed value that is afterwards immutable and treated as “truly final” by the JVM, which allows it to apply optimizations like constant folding. This allows for lazy initialization that improves performance through laziness as well as better JIT opimizations.
