JEP proposed to target JDK 26: 526: Lazy Constants (Second Preview)

[Mark Reinhold]

The following JEP is proposed to target JDK 26:

  526: Lazy Constants (Second Preview)
       https://openjdk.org/jeps/526

  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.

Feedback on this proposal from JDK Project Committers and Reviewers [1]
is more than welcome, as are reasoned objections.  If no such objections
are raised by 20:00 UTC on Wednesday, 12 November, or if they’re raised
and then satisfactorily answered, then per the JEP 2.0 process proposal
[2] I’ll target this JEP to JDK 26.
