;; Calling java.lang.Integer and java.lang.Long static members.
;;
;; Same three-layer flow as Math/* and System/*: gloat rewrites each
;; `Integer/*` and `Long/*` symbol to glojure's javacompat bridge, which
;; forwards to gojava's typed Go ports.
;;
;; `Integer/MAX_VALUE` is an int32 with the JVM-faithful value 2^31 - 1,
;; not Go's platform-dependent `math.MaxInt`. `Long/MAX_VALUE` is the
;; full int64 max.
