I was deceived by the error message. Since I had only changed the Clojure
version 1.9 => 1.10, and since the warning mentioned only Clojure code:
WARNING: Illegal reflective access by
clojure.lang.InjectedInvoker/0x0000000800231c40
(file:/home/alan/.m2/repository/org/clojure/clojure/1.10.0/clojure-1.10.0.jar)
I thought the problem was within the Clojure source. After investigating
further, the problem was indeed a lack of type-hinting in a dependent
library (Enlive). The fix was to add 2 type hints to a function call:
(.parse
^java.io.InputStream s ; actual type =>
java.io.BufferedInputStream
^org.xml.sax.helpers.DefaultHandler ch ; actual type =>
net.cgrand.xml.proxy$org.xml.sax.ext.DefaultHandler2
)
A Pull Request has been filed. Much thanks to Andy Fingerhut for pointing
me in the right direction.
