/**
        File Name:      boolean-004.js
        Description:

        A java.lang.Boolean object should be read as a JavaScript JavaObject.
        To test this:

        1.  The object should have a method called booleanValue(), which should
            return the object's value.
        2.  The typeof the object should be "object"
        3.  The object should have a method called getClass(), which should
            return the class java.lang.Boolean.
        4.  Add a method to the object's prototype, called getJSClass() that
            is Object.prototype.toString.  Calling getJSClass() should return the
            object's internal [[Class]] property, which should be JavaObject.
