There's a proposal to dissolve the Kulla project (the project that introduced JShell into JDK), and use the compiler-dev mailing list instead of kulla-dev:
https://mail.openjdk.org/pipermail/kulla-dev/2025-June/005928.html

The file mappings used for JShell should be merged into the compiler label, so that changes touching JShell get the compiler label, and the e-mails are sent to compiler-dev.
