IDE error on namespaced map in REPL

[atroche]

Hello!

With clojure 1.9.0-alpha10, when I do:

#:: {:a 1}
=> #:user{:a 1}

I get an IDE error:

String index out of range: -1
java.lang.StringIndexOutOfBoundsException: String index out of range: -1

Not a huge deal, just thought you might want a heads up =)
