title: JTable rowCount problem
body: <p>I generated a Swing interface with NetBeans. Everything works well, until I change <code>rowCount</code> to 4096. Now I get the exception <code>NoClassDefFoundError</code>. I've tested that from <code>rowCount</code> 3850 it breaks. Is this is a bug, or something else; all tips are welcome. How can I increase that <code>rowCount</code> correctly?</p>
