        File Name:      object-002.js
        Description:

        Given a JavaObject, calling the getClass() method of java.lang.Object
        should return the java.lang.Class of that object.

        This tests the LiveConnect function getClass( <javaobject> ), which
        should be a defined function that returns the JavaClass object for
        a JavaObject instance.

        The absense of the getClass function is
        http://scopus/bugsplat/show_bug.cgi?id=106560

        To test this:

        1.  Create a JavaObject by instantiating a new object OR call
            a java method that returns a JavaObject.

        2.  Call the getClass() function with the object as its argument.

        3.  Compare the result of 2 to the Class.
