Java/swing font resize not working across platforms

I have a swing application with this code, which attempts to resize the font of a component:

Font f = new Font(Font.SERIF,Font.PLAIN,16);
component.setFont(f);

The program loads with 14 point font, and I include a component which lets the user resize the component to 16 point font as above. When I run this on the computer I compiled it on (Debian), it works as intended, but I tested it on a Mac and a Windows computer and the font resizing feature doesn't work at all. However, on all platforms the font is serif. Any ideas why this is happening?

The component's default UI delegate on your platform may be pre-empting your setting. In the alternative, consider one of the following:

  • Use deriveFont() on the existing font, illustrated here.

    component.getFont().deriveFont(16f)

  • Use an available sizeVariant, illustrated here.

  • Use a custom UI delegate, illustrated here and here.
