-/**
- * Activator for netconf SSH bundle which creates SSH bridge between netconf client and netconf server. Activator
- * starts SSH Server in its own thread. This thread is closed when activator calls stop() method. Server opens socket
- * and listen for client connections. Each client connection creation is handled in separate
- * {@link org.opendaylight.controller.netconf.ssh.threads.SocketThread} thread.
- * This thread creates two additional threads {@link org.opendaylight.controller.netconf.ssh.threads.IOThread}
- * forwarding data from/to client.IOThread closes servers session and server connection when it gets -1 on input stream.
- * {@link org.opendaylight.controller.netconf.ssh.threads.IOThread}'s run method waits for -1 on input stream to finish.
- * All threads are daemons.
