Cannot be run with -Dclojure.core.async.go-checking=true

[vemv]

Context

Release 0.5.527 on 2019.11.12
Add system property clojure.core.async.go-checking that will throw if core.async blocking ops (>!!, <!!, alts!!, alt!!) are used in a go block

https://github.com/clojure/core.async/blob/91e132b8ffa90af9eaa21d8e5c4e78369fdfea1a/README.md

Describe the Bug

If I run trapperkeeper with the -Dclojure.core.async.go-checking=true JVM flag, I can hit the exception attached at the bottom

Steps to Reproduce

A bit hard to, especially respecting IP concerns, but if that helps, I'd suggest that you run the CI build with the flag set. Afer all, it's reasonable that modern core.async usage should be able to satisfy this safety flag.

Environment

• TK 3.0.0
• core.async >= 0.5.527
• macOS
