Component JButton does not show all button text, when sertain fonts are set for this button.
Frame window of the following test contains two buttons ("Next font" and "Previous font" - at left) and
tested JButton component (at right).
By clicking on buttons "Next" and "Prev" you can change fonts of tested button.
In many cases you'll see that all text does not appear in the button label.

Note that the TextButton components look correctly with any font.
