Hi @wuseal, thanks for the report.
Could you change runBlocking to launch(Dispatchers.Unconfined)?

I'm seeing this same issue on 1.2.0-rc using the Native client on Linux. I've tried using launch(Dispatches.Unconfined) as suggested by @e5l and the exception appears to be the same:

Don't freeze your HttpClient, it doesn't work.
That means don't put it inside an object for example, or inside an instance of a class stored inside an object, etc

Hello, World! The issue is marked as fixed but I can still reproduce it (with 1.2.4).

Using @Ribesg trick worked too for me (using a class instead of an object- but I understood this was not necessary after the fix?
