JSR 401 (Java SE 26): JEP Proposed to Target: 526: Lazy Constants (Second Preview)

[Iris Clark]

The following JEP with scope "SE" has been 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.

The announced deadline for feedback to jdk-dev is Wed12 Nov 20:00 UTC:

    https://mail.openjdk.org/pipermail/jdk-dev/2025-November/010588.html

If there are no unresolved objections at that time, then the JEP will be moved
to the Targeted state, indicating that the feature is expected to appear in
the specified release of the JDK Project.  For more information about states,
see the JEP Process document:
