36  * This class is used as a "proxy" or adapter between the remote business
37  * interface proxy and the EJBObjectInvocationHandler. An instance of this
38  * class is created for each remote business interface of a bean. All
39  * java.lang.Object methods are handled by this InvocationHandler itself
40  * while the business interface methods are delegated to the delegate
41  * (which is the EJBObjectInvocaionHandler).
