JSR 401 (Java SE 26): JEP Proposed to Target: 500: Prepare to Make Final Mean Final

[Iris Clark]

The following JEP with scope "SE" has been proposed to target JDK 26:

  500: Prepare to Make Final Mean Final
       https://openjdk.org/jeps/500

  Summary: Issue warnings about uses of deep reflection to mutate
  final fields.  These warnings aim to prepare developers for a future
  release that ensures integrity by default by restricting final field
  mutation, which will make Java programs safer and potentially faster.
  Application developers can avoid both current warnings and future
  restrictions by selectively enabling the ability to mutate final fields
  where essential.

The announced deadline for feedback to jdk-dev is Thu 6 Nov 20:00 UTC:

    https://mail.openjdk.org/pipermail/jdk-dev/2025-October/010571.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:
