/**
   File Name:      number-001.js
   Description:

   Accessing a Java field whose value is one of the primitive Java types
   below, JavaScript should read this as a JavaScript Number object.
   byte
   short
   int
   long
   float
   double
   char

   To test this:
   1.  Instantiate a new Java object that has a field whose type one of
   the above primitive Java types, OR get the value of a class's static
   field.
   2.  Check the value of the returned object
   3.  Check the type of the returned object, which should be "object"
   4.  Check the class of the returned object using Object.prototype.toString,
   which should return "[object Number]"

   It is an error if the type of the JavaScript variable is "number" or if
   its class is JavaObject.
