I don't quite understand that statement; the TCP-level keepalive
should only apply to a remote call in progress, and it is about
detecting loss of connection (and closing sockets) because of a
network partition or a hard crash of the remote host.  During normal
operation, idle JRMP connections are closed by the client (caller)
side according to that timeout that is controlled by the system
property "sun.rmi.transport.connectionTimeout" (default value of 15000
or 15 seconds).
