Strange JButton appearance for all LAFs except Windows

Question

It took me a while to figure out how to repeat this problem, but I finally did. I have a simple BoxLayout container in a JFrame, and with Windows Look and Feel it looks as expected. With any other LAF on my system (Metal, Windows Classic, CDE/Motif) all buttons except one are displayed as if their insets are null. The button border is confined very close to the button text. Calling setSize() on the button doesn't make any difference.
What makes it strange is that I can't see why one button is displayed properly. And even stranger is the fact that it's not the button position that determines which one looks correct. Take a look at the test code below, which is a stripped down executable extract of my program. The JButton object "settings" is always displayed correctly, even If you re-arrange the arguments to the cbButtonPanel.add() methods so that "settings" is in a different position. I can't see anything different about how settings is defined or configured compared to the other buttons. I even gave them the same button text to eliminate that as the source of the difference.
If you run the test code with no program argument, it will default to Windows Look and Feel, and the buttons will look as I intended them to. But enter a LAF name for the argument (See the names provided on the console when you run the program) other than Windows and you'll see that all but one button are not displayed properly. (Note that for any multi-word LAF name, e.g. Windows Classic, you need to enclose the argument in quotes.)
The code seems to be a straightforward implementation of a BoxLayout managed container, as documented in the javadocs and the tutorial. Am I doing something wrong that Windows LAF lets me get away with?

Answer 1

The problem turned out to be the setBorder() invocations I was making on the JButtons. This was left over from when I originally used a null layout manager, and the setBounds() calls were making the buttons appear at their desired size. The clue came when I discovered that I was setting the border on all buttons except settings, the one that was behaving properly. Why it behaved as expected with Windows LAF I have no idea.
