Modifying linked/set fails in CLJ and CLJS

[LukasRychtecky]

Hello,

I've tried to use linked/set, but all following operations failed:

CLJ

dev=> (linked/set 4)
java.lang.AbstractMethodError: Method linked/set/LinkedSet.toArray()[Ljava/lang/Object; is abstract

same result for calling

(into (linked/set) [1])

and

(conj (linked/set) 1)

CLJS:

I am using [org.clojure/clojure "1.9.0-alpha17"] and [org.clojure/clojurescript "1.9.671"].
Am I doing something wrong?

Thanks for answering.
