Java – getting rid of Border on Top

I had this problem that my applet was always showing this 5 pixel border at the top – like you can see in the left Screenshot…

…so I was looking for a resulotion for that. In the end it was hard to guess but simple: I just had to add the line setLayout(new BorderLayout()); to make it work according to the Image on the right. But why does it have this 5 pixel? I have no clue. Doesn’t really make sense. Do you know? Here is my Code for your testing:

import java.applet.Applet;
import java.awt.BorderLayout;
import java.awt.Color;
import javax.swing.JLabel;
public class Main extends Applet{
	private static final long serialVersionUID = 1L;
	JLabel myJLabel;
	public void init()
		myJLabel = new JLabel ("Test");
		// Prevent border on top
		setLayout(new BorderLayout());
		this.add("Center", myJLabel);

PS: You may want to set the Background-Color to black – otherwise you will have ugly green flickers…
