The setBackground method in JLabel does not seem to be working.

import java.awt.*;
import javax.swing.*;

public class LabelTest {

	public static void main(String args[]) {
		JFrame frame = new JFrame();
		Label label = new Label("This works!");
		JLabel jLabel = new JLabel("This does not!");

		Container contentPane = frame.getContentPane();
		FlowLayout flowLayout = new FlowLayout();
		contentPane.setLayout(flowLayout);

		label.setForeground(Color.white);
		jLabel.setForeground(Color.white);

		label.setBackground(Color.green);
		jLabel.setBackground(Color.red);
		contentPane.add(label);
		contentPane.add(jLabel);
		frame.setSize(350, 250);
		frame.setVisible(true);
	}
}
