/**
   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.
