title: Java - Detecting client crash with RMI
body: <p>I have created a RMI connection but I do not know how to notify the server when the client ends or crashes. I have found the <i>unreferenced()</i> method, but it does not work. Any idea?
  <br>(the server is multiclient, there is only one kind of object passed to the client but any client has a different instance of it).<br>
  Thanks.</p>
