I'm trying to find my way into ClojureScript, currently following the modern clojurescript tutorial using boot as my build tool. Unfortunately I keep running into a Java ClassNotFoundException concerning javax.xml.bind.DatatypeConverter. Googling only reveals a known problem with the switch from Java 8 to 9. I'm running openJDK 11.0.4 however, so that's hardly my case.
Here's what happened so far. Initially I had no luck compiling Clojurescript at all. I would get:
java.lang.ClassNotFoundException: javax.xml.bind.DatatypeConverter
clojure.lang.Compiler$CompilerException: java.lang.ClassNotFoundException: javax.xml.bind.DatatypeConverter, compiling:(cljs/closure.clj:1:1)
I was able to get around that problem by specifying the ClojureScript version adding [org.clojure/clojurescript "1.10.520"] to my build.boot file, which currently looks as follows:
(set-env!
:source-paths #{"src/cljs"}
:resource-paths #{"html"}
:dependencies '[
[adzerk/boot-cljs "2.1.5" :scope "test"]
[org.clojure/clojurescript "1.10.520"]
[pandeiro/boot-http "0.8.3"]
[org.clojure/tools.nrepl "0.2.13"]
[adzerk/boot-reload "0.6.0"]
[adzerk/boot-cljs-repl "0.4.0"]
[cider/piggieback"0.4.1" :scope "test"]
[weasel "0.7.0" :scope "test"]
[nrepl "0.6.0" :scope "test"]
])
(require '[adzerk.boot-cljs :refer [cljs]]
'[pandeiro.boot-http :refer [serve]]
'[adzerk.boot-reload :refer [reload]]
'[adzerk.boot-cljs-repl :refer [cljs-repl start-repl]])
The problem now is back with a vengeance though within the ClojureScript REPL. I successfully connect to the nREPL started by boot getting into the boot.user Namespace (I use the following boot command to start the nREPL boot serve -d target watch reload cljs-repl cljs target and connect to it via boot repl -c).
To my understanding this opens an ordinary Clojure REPL not a ClojureScript REPL. Trying to start the latter by typing (start-repl) gives me almost the exact same error as the one above. Only that it was trying to compile org/httpkit/server.clj:1:1 rather than cljs/closure.clj:1:1.
To me it seems that the ClojureScript REPL wants to use some default Clojurescript version which apparently differs from the one specified in the build.boot file. I don't really understand either why I had to deviate from the tutorial by specifying the ClojureScript version there in the first place.
Any help with this will be greatly appreciated!
Best to all of you

Addenda:
My System: ubuntu 18.04
My boot.properties:
#http://boot-clj.com
#Tue Sep 17 12:18:55 CEST 2019
BOOT_VERSION=2.8.3
BOOT_CLOJURE_VERSION=1.8.0
BOOT_CLOJURE_NAME=org.clojure/clojure
[http-kit "2.3.0"]I still feel there must be something wrong under the hood if I have to specify these manually while tutorial doesn't even mention them… Why would my setup default to apparently deprecated versions of libs (the tutorial is a bit dated)?
