   * An example object macro written in Java.
   *
   * To define a Java object macro, you must implement the interface
   * com.rivescript.ZzObjectMacro and register it using setSubroutine().
   *
   * This macro does two things: returns their message reversed, and sets
   * a user variable named `java`.
   *
   * This implements the `reverse` object macro used in Aiden/obj-java.rive
   *
   * See RSBot.java for more details.
