from 1.5.x?

the only change in 1.6 is to dynaload the ioc-macros namespace (which uses the analyzer) in the Clojure version

I'm assuming you're using the cljs side though

no, the CLJ version

are you aot compiling?

this happens when loading shadow-cljs, which uses core.async. didn't even get to the CLJS compiler yet. from 1.5.648 yes

it is a AOT compiled release yes

if aot compiling, then the analyzer will be dynamically loaded (requiring-resolve) during compilation and is not needed at runtime

I'm not sure how that translates to your error though

maybe has something to do with compilation order?

is this lein aot or tools.build or something else?

lein aot building two variants https://github.com/thheller/shadow-cljs/blob/master/project.clj#L79-L88

aot compile works fine though, it just happens when running after

this change will definitely affect when/if tools.analyzer is going to be loaded during aot. in the aot'ed classes, can you diff the set of compiled classes from clojure.tools.analyzer. when using core.async 1.5.x vs 1.6.x ? I would consider maybe including one or more of the analyzer entry points in the compiled namespace list at the top

or just clojure.core.async.impl.ioc-macros

sorry, got distracted. adding the clojure.core.async.impl.ioc-macros to the :aot list seems to have fixed it

👍

it does seem to cause trouble for other people as well, even when fixed in the shadow-cljs part. https://clojurians.slack.com/archives/C6N245JGG/p1668672181550289

I'll see if I can figure out a minimal repro later

downgraded core.async for now
