Getting a stack overflow running datomic Ion cast in cider

I was getting a StackOverflowError running this in CIDER while developing with Datomic Ions

	(ns bug-demo
	(:require [datomic.ion.cast :as cast]
	[clojure.java.io :refer [output-stream]]))
	(cast/initialize-redirect :stdout)
	(cast/event {:msg "ShouldNotCauseAStackOverflowErrorInCider"})

For some reason the output stream created ends up being referential with the nrepl PrintStream implementation. Changing it from :stdout to :stderr seems to solve the problem:

	(ns bug-demo
	(:require [datomic.ion.cast :as cast]
	[clojure.java.io :refer [output-stream]]))
	(cast/initialize-redirect :stderr) ; instead of :stdout
	(cast/event {:msg "ShouldNotCauseAStackOverflowErrorInCider"})
