code: public SshClient connect(SshTransport transport, String username,
  			SshContext context) throws SshException {
  		return connect(transport, username, false, context);
  	}
docs: See {@link connect(SshTransport, String)} for full details. This method
  optionally allows you to specify a context to use. Normally you would
  reused an {@link SshConnector} instead of calling this method directly.
