| * This class is a facade for the remote and local SerialContextProvider The |
| * need for this class arose from the fact that we wanted to have a way of |
| * lazily initializing the Remote SerialContextProvider. The TransientContext |
| * member field has to be shared across both remote and local |
| * SerialContextProvider. It could have been a static variable but to avoid |
| * issues of static variables with multiple threads, etc, this class has been |
| * designed. The ORB needs to be initialized before the call to |
| * initRemoteProvider() |
