title: Loosing vertical scrollbar in netbeans nimbus LAF
body: <p>I'm using Netbeans 8.0.2 and the Nimbus Look And Feel.
  At a certain point, when the vertical scroll slider becomes small, it disappears. </p>
  
  <p>Has anyone the same behavior or any fix for that problem? </p>
  
  <p>EDIT:
  This happens only in Nimbus and Dark Nimbus LAF</p>
