The following JEP is 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.

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 16:00 UTC on Tuesday, 5 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 24.
