I tried overloading -init, but I get the same problem.
java.lang.ClassFormatError: Duplicate field name&signature in class
file test/gui/button (repl-1:2)
e.g.:
(ns test.gui.button
(:gen-class
:extends javax.swing.JButton
:constructors {[] [String]}
:init init))
(defn -init
([] [["Click me"] nil])
([one-arg] [["Click me"] nil]))
