I'm trying to use http-kit with the sni client:

$ clj
Clojure 1.10.2-alpha1
user=> (require '[org.httpkit.client :as client])
nil
user=> (require '[org.httpkit.sni-client :as sni-client])
nil
user=> (alter-var-root #'org.httpkit.client/*default-client* (fn [_] sni-client/default-client))
#object[clojure.lang.Delay 0x2b289ac9 {:status :pending, :val nil}]
user=> @(org.httpkit.client/get "")
{:opts {:method :get, :url ""}, :error #error {
 :cause nil
 :via
 [{:type java.lang.NullPointerException
   :message nil
   :at [sun.net.util.IPAddressUtil textToNumericFormatV4 "IPAddressUtil.java" 49]}]

It does seem to work on Java 1.8

@borkdude not sure. Worked for me, but I'm using OpenJDK-GraalVM-11 Lemme grab a copy of AdoptOpenJDK and investigate
