* 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()
