Clojurians Log v2

we're upgrading out boot cljs build to JVM 11. We're getting a lot more advanced compilation errors than before. E.g. now I'm looking at:

Uncaught TypeError: Cannot read property '$cljs$core$IFn$_invoke$arity$3$' of undefined
    at $reagent$dom$render_comp$$ (app.js:33023)
    at $reagent$dom$render$cljs$0core$0IFn$0_invoke$0arity$03$$ (app.js:33034)
    at $dre$core$mount_components_BANG_$$ (app.js:60358)

I'm not sure if this is a CLJS or boot problem

I have now narrowed this problem down to boot tooling. I've ported our CLJS build to deps.edn and there it works just fine on JVM 11

Anyone else doing advanced builds with boot on JVM11?

unrelated problem: when I generate js with deps.edn and publish this to a resource path that's watched by boot, I get this error: 2019-10-25 14:16 java[89795] (FSEvents.framework) FSEventStreamStart: register_with_server: ERROR: f2d_register_rpc() => (null) (-21)
