title: ProGuard breaks Java application - no text, no images
body: <p>I'm trying to use <a href="http://proguard.sourceforge.net/" rel="nofollow">ProGuard</a> to obfuscate a Java application. I'm experiencing a problem where all of my text and images disappear from the GUI (Swing) forms. I've tried disabling optimizations and including more libraries, but nothing seems to be working.</p>
  
  <p>I've inspected the output generated by the obfuscator with a decompiler, and my resource paths seem to still be correct.</p>
  
  <ol>
  <li>Do I need to be including more core Java libraries outside of jre/lib/rt.jar?</li>
  <li>Are there more settings I should disable?</li>
  <li>...other suggestions?</li>
  </ol>
  
  <p>Thanks.</p>
