The following JEP with scope "SE" has been proposed to target JDK 24:

 488: Primitive Types in Patterns, instanceof, and switch (Second Preview)
       https://openjdk.org/jeps/488

  Summary: Enhance pattern matching by allowing primitive types in all
  pattern contexts, and extend instanceof and switch to work with all
  primitive types.  This is a preview language feature.

The announced deadline for feedback to jdk-dev is Tue 5 Nov 16:00 UTC:

    https://mail.openjdk.org/pipermail/jdk-dev/2024-October/009580.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:

    https://openjdk.org/jeps/1

A dashboard that lists JEPs with "SE" scope may be found via a link on this

Iris
