timeout in wating for rekeying process.

[Jon Gorrono]

I have looked thru the code and I see that this occurs if the timeout passed into connect() is exceeded while negotiating... but what it confounding to me is that this message sometimes occurs immediately. My timeout is a static value in the same class and so cannot be null and it is set to 20000.

jsch.setKnownHosts(knownHostsFile);
jsch.addIdentity((String)settings.get(SSHTunnel.KEY_IDFILE), "");
session = jsch.getSession((String)settings.get(SSHTunnel.KEY_REMOTEACCOUNT), (String)settings.get(SSHTunnel.KEY_REMOTEHOST));
session.setDaemonThread(true);
session.setServerAliveCountMax((Integer)settings.get(SSHTunnel.KEY_SERVER_ALIVE_COUNTMAX));
session.setServerAliveInterval((Integer)settings.get(SSHTunnel.KEY_SERVER_ALIVE_INTERVAL));
session.connect(TIME_WAIT);
assigned_port=session.setPortForwardingL(
(Integer)settings.get(SSHTunnel.KEY_LOCALPORT),
(String)settings.get(SSHTunnel.KEY_REMOTEHOST_TUNNEL),
(Integer)settings.get(SSHTunnel.KEY_REMOTEPORT));

More supporting information....
code:

 line 0: private static int TIME_WAIT = 20000;
...
 line 1: l.debug("starting connection @ " + System.currentTimeMillis());
 line 2: session.connect(TIME_WAIT);
 line 3 l.debug("starting tunnel @ " + System.currentTimeMillis());

log output:

2014-06-06 19:59:13 DEBUG SSHTunnel$Tunnel:125 - starting connection @ 1402109953613

... line 3 is never reached after the exception and the logoutput from line 1 is in the same second as the log output just before the connection attempt
