/**
   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(  ), 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.
