>   JVM, enabling the same performance optimizations that are enabled
>   by declaring a field final.  Compared to final fields, however,
>   stable values offer greater flexibility as to the timing of their
>   initialization.  This is a preview API.

Hearing no objections, I’ve targeted this JEP to JDK 25.
