title: Netbeans Download Javadoc repeatedly
body: <p>I work with Netbeans 7.0.1 for a research project. My issue is that each time I want to check the javadoc for a given function or class (from the auto-completion menu), Netbeans downloads Javadoc and caches it only while it's running. If I restart Netbeans, I have to download the javadoc again.</p>
  
  <p>Is there a way to tell Netbeans to cache the Javadoc for ever?
  I work with Mac OS.</p>
