title: Are there any java library for thumbnails generation?
body: <p>I need some smart enough thumbnail generation lib to use it in my java app. I've found appropriate code <a href="http://www.philreeve.com/java_high_quality_thumbnails.php" rel="noreferrer">here</a> but I'm not sure about possible licensing issues.</p>
  
  <p>Are there any free appropriate libraries?</p>
