title: How to inform the user that a specific Tab in a JTabbedPane needs attention?
body: <p>Say you have a user interface with five or more tabs, and you need to inform the user that tab "2" needs attention.</p>
  
  <p>Is there a way to do this? For example make the tab flash orange, or change the colour of the tab? I have had no success with requestFocus.</p>
  
  <p>Edit: I am also interested in knowing how to force the focus on tab 2 if it ispossible.</p>
