;; Polymorphic dispatch on argument type.
;;
;; The JVM overloads `Math.abs` on int, long, float, and double, and the
;; return type matches the argument type. Go has no overloading -- gojava
;; exposes typed names (`AbsInt`, `AbsLong`, etc.) and the bridge picks
;; the right one at runtime based on the actual value type.
;;
;; The integer call returns an integer; the double call returns a double.
