title: Working with decompiled java code
body: <p>In my recent project, we are in need to modify some business rules, but we don't have source code.</p>
  
  <p>I took latest production deployed jar file and opened it through JD-gui. By using option save All resources i am able to get de compiled java files. Now my questions are:</p>
  
  <ol>
  <li><p>I see that decompiled java code is having unnecessary line comments on each and every lines. Is there any way to avoid them?</p></li>
  <li><p>If i make the changes to some file and then compile the code again and send the jar to production, will there be an any hidden challenges?</p></li>
  </ol>
