Is reflection necessary to encode or decode XML namespace names? This reflection is in a "definline", so it might be sailing into undesired headwinds.
This is with clojure.data.xml 0.2.0-alpha6, the latest that I saw on Maven Central; and OpenJDK 11.
(set! *warn-on-reflection* true)
(require '[clojure.data.xml :as data.xml])
Reflection warning, clojure/data/xml/jvm/name.clj:35:1 - call to static method decode on java.net.URLDecoder can't be resolved (argument types: unknown, java.lang.String).
Reflection warning, clojure/data/xml/jvm/name.clj:38:1 - call to static method encode on java.net.URLEncoder can't be resolved (argument types: unknown, java.lang.String).
I guess it would be safe and efficient to type-hint the "unknown" first parameter as a String. The URLEncoder/URLDecoder methods in question are overloaded, but the signatures all require a String as the first parameter.
