While waiting for an event notification, if the connection is closed by the
server (or the client), the listener is notified via its namingExceptionThrown()
method. However, this doesn't happen for UnsolicitedNotificationListeners.
If this were to happen for unsol listeners, then clients can use
this as a general way to monitor the connection for liveness.

Here is the customer's email.

Rosanna, you might like to know that this doesn't happen for
UnsolicitedNotificationListeners, only regular
Object/NamespaceChangeListeners.
