        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.
