title: VisualGC Download for offline installation
body: <p>I need to install the visualGC plugin for jvisualvm on an <strong>offline</strong> machine.
  So I have to download the *.nbm file first. The links on <a href="http://visualvm.java.net/pluginscenters.html" rel="nofollow noreferrer">this</a> site are all down (http/404).</p>
  
  <p>Where can I get this file?</p>
