title: Disabling space bar triggering click for JButton
body: <p>JButtons consider pressing the space bar to be the same as clicking on the JButton (assuming the JButton has the focus, which I am assuming here). Is there a way to turn off this behavior so they ignore pressing the space bar?</p>
  
  <p>Also, more generally, is there a technique for doing this with <code>AbstractButtons</code>?</p>
