When manipulating the font size of an HTML JLabel using the <font size='+1'> tag, the displayed font actually gets smaller, instead of larger. This is probably due to the code starting the calculation at a smaller font-size than the non-HTML JLabel.
This only happens with the Windows Look and Feel.
Steps to reproduce:
Run the code:
-----------------------
import javax.swing.*;
import java.awt.*;
import static javax.swing.JFrame.EXIT_ON_CLOSE;
public class JTextAreaTest {
public static void main(String[] args) {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception e) {
e.printStackTrace();
}
SwingUtilities.invokeLater(() -> {
final JFrame frame = new JFrame();
frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
frame.setBounds(500, 500, 300, 150);
frame.setLayout(new BorderLayout());
final JLabel label = new JLabel("Regular Label");
frame.add(label, BorderLayout.NORTH);
final JLabel htmlLabel0 = new JLabel("<html><font size='+1'>HTML Label +1</font></html>");
final JLabel htmlLabel1 = new JLabel("<html><font size='+0'>HTML Label +0</font></html>");
frame.add(htmlLabel0, BorderLayout.CENTER);
frame.add(htmlLabel1, BorderLayout.SOUTH);
frame.setVisible(true);
});
}
}
--------------------------
Attached screenshot demonstrates that the +1 font size is actually slightly smaller than the regular font. Also +0 is tiny, even though it should have no effect whatsoever.

frame.setVisible(true);
});
