        File Name:      number-001.js
        Description:

        If a Java method returns one of the primitive Java types below,
        JavaScript should read the value as JavaScript number primitive.
        *   byte
        *   short
        *   int
        *   long
        *   float
        *   double
        *   char

        To test this:

        1.  Call a java method that returns one of the primitive java types above.
        2.  Check the value of the returned type
        3.  Check the type of the returned type, which should be "number"

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