I have problems getting "Interrupt Running Evaluations" to work in a plain project. I've confirmed that the jvm option is applied -Djdk.attach.allowAttachSelf . deps.edn: {:extra-paths ["src"] :aliases {:allow-attach-self {:jvm-opts ["-Djdk.attach.allowAttachSelf"]}}} jack in command: clojure -Sdeps '{:deps {nrepl/nrepl {:mvn/version,"1.5.1"},cider/cider-nrepl {:mvn/version,"0.58.0"}}}' -M:allow-attach-self -m nrepl.cmdline --middleware "[cider.nrepl/cider-middleware]" forever.clj: (ns forever) (comment (while true) ;; cannot be interrupted ) JVM: OpenJDK 64-Bit Server VM (24+36-3646, mixed mode, sharing) Java: version 24 2025-03-18, vendor Oracle Corporation running wsl2 ubuntu on windows 11. when nothing is running and i call "Interrupt Running Evaluations" I get a popup with: 'Interruption command finished (unknown results)' But when (while true) is running there is no such popup, and I need to restart the repl process. Tried re-installing the calva extension, no change. Any suggestions?

Maybe (while true) never returns the repl connection back so the interrupt is never sent… You can check what the nrepl message log says. There’s a command for enabling that log.

Think this is it?:

Has anyone been able to repro https://github.com/BetterThanTomorrow/calva/issues/2979 or have any insight into it? Calva is still reporting nREPL 1.5.1 as the latest version at startup...

I see the same issue on my mac.
