title: Decompile Java Application packed with launch4j
body: <p>I have a Java application that was converted to an .exe with launch4j. For several reasons I need to get access to the class files of the application.</p>
  
  <p>The first thing I tried was unpacking the exe with 7zip. That way I get a handful of class files, but definately not the whole application packed in the exe (the class files seem to belong to launch4j).</p>
  
  <p>What other options are there?</p>
