>   Summary: Introduce an API for lazy constants, which are objects that
>   hold unmodifiable data.  Lazy constants are treated as true constants
>   by the JVM, enabling the same performance optimizations that are
>   enabled by declaring a field final.  Compared to final fields, however,
>   lazy constants 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 26.
