title: setBorder method for JLabel causing paint problem
body: <p>I have a custom class that extends JLabel.  For specific instances of that class, I want to add some spacing to the text on the left side.  I need the spacing as I'm setting the background of this JLabel and I don't want the text to bump up right next to the edge of the colored background.  I fished around quite a bit and implemented this (inside the paint function):</p>
  
  <pre><code>if (condition) {
      bgColor = Color.red;
      setBackground(bgColor);
      setOpaque(true);
      // This line merely adds some padding on the left
      setBorder(BorderFactory.createEmptyBorder(0, 10, 0, 0));
  }
  else {
      setOpaque(false);
  }
  </code></pre>
  
  <p>This appears to work in that it adds the spacing I want, however it has an unfortunate side effect in that it appears to break the repainting of the whole rest of the application...it appears that only that particular component is repainting and not the rest of the application.  I eventually tracked it down to the setBorder call specifically...setting ANY kind of border appears to cause the same broken behavior.  We have two different versions of our application, one that runs in Java 1.5 and one that runs in Java 1.6, the Java 1.6 version appears to work correctly while the Java 1.5 version doesn't.  It is not possible to upgrade the older version to Java 1.6...I need something that will work in Java 1.5.  Also, I tried this (just to see what it looked like):</p>
  
  <pre><code>setHorizontalTextPosition(JLabel.CENTER);
  </code></pre>
  
  <p>And that also appears to break the repainting in exactly the same way.  I looked through the source of our application and found other places where we set borders (including empty borders), but couldn't find any on JLabels (only panels, buttons, etc).  Anybody see anything like this before?  Know how to fix it?  Or perhaps another way to obtain the spacing I require that may work around the bug?  Thanks.</p>
