> This is similar to the one mentioned in the issue 286. Since there are no ways found
to reopen the issue (which was already marked as 'Resolved'), I'm creating a new issue.
> As a solution for the issue reported in 286, it is suggested to add a shutdown hook.
But it seems it won't address the cases of unexpected network disconnects as given in the
following scenario.
> 1. User1 logs in. The status is set as 'Available' by default.
> ==> User1's status is reflected in the messenger window of other logged in users.
> 2. Disconnect User1's workstation from the network.
> ==> Other user's list disappears from User1 messenger window.
> 3. Check the status of User1 from the messenger window of other logged in users.
> ==> User1's status still remains in the same for all other users.
> Expected: User1's status should be made offline to other users as soon as the network
disconnects.
> The questions is how to detect the unexpected network disconnects for User1 and broadcast
the status (as offline) to other logged-in users.
> Thanks...
