AOT issues with clj_http.headers.HeaderMap
I'm following the guide for using AOT. This works ... except for clj-http.
The error I'm getting is not when compiling but when loading the compiled classes (rather than clj files):
Execution error (ClassNotFoundException) at jdk.internal.loader.BuiltinClassLoader/loadClass (BuiltinClassLoader.java:641).
clj_http.headers.HeaderMap
When I rm -rf classes/clj_http, it works again.
Unfortunately I couldn't come up with a simple repro case - when I tried it outside of the main app, it worked. Not sure why - race condition?
I suspect (but cannot prove) that the AOT incompatibility is due to the use of potemkin.
There's an earlier report from 2016, but I'm not using Leiningen https://clojurians.slack.com/archives/C0AB48493/p1469153573000034
clj-http/clj-http 3.12.3
potemkin/potemkin 0.4.5
BTW uberjars work fine - the issue happens only when AOT-compiling for development
After some investigations, here's what I learned:
• Part of the problem seems to be loading namespaces in user.clj. After stopping to load stuff in user.clj, the problem went away for me (this explains why lein uberjar etc doesn't have the problem)
• Generally what seems to be happening is this: I'm loading clj-http and then compiling it. "Something is loading clj-http before you do the aot compilation, and on the second loading (for aot) potemkins type definition stuff no-ops, so the class doesn't get written to disk"

This still seems like a wrinkle in clj-http, though maybe not a bug (maybe in potemkin?)
Something is loading clj-http before you do the aot compilation
Could this be something internal to leiningen itself that's loading clj-http?
I'm using tools.deps for this report. I'm pretty sure the problem is because the lib was loaded in user.clj, then compiled
