Can anyone please help , why this is happening.
I am using Tiger VNC , running on RHEL 6

code:

public static void main(String[] args){
Socket s = new Socket("192.168.1.17", 5900); 
s.setSoTimeout(1000);
s.setKeepAlive(true);
ConnectionController cc = new ConnectionController(s);
cc.openConnection(0);
cc.setPixelFormat(0, "Truecolor", 32, 0); 
cc.start(0);
Thread.sleep(2000); 
VNCScreen vnc = new VNCScreen();  
cc.closeConnection()
