JSR 500 (Java SE 25): JEP Proposed to Target: 502: Stable Values (Preview)

[Iris Clark]

The following JEP with scope "SE" has been proposed to target JDK 25:

  502: Stable Values (Preview)
       https://openjdk.org/jeps/502

  Summary: Introduce an API for stable values, which are objects that
  hold immutable data.  Stable values are treated as constants by the
  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.

The announced deadline for feedback to jdk-dev is Fri 7 Mar 20:00 UTC:

    https://mail.openjdk.org/pipermail/jdk-dev/2025-February/009787.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:
