title: How to decompile Java class files which jd-gui decompiler is unable to decompile?
body: <p>We accidently got some JAVA source files deleted from the system.</p>
  
  <p>This happened when We checked out a folder from repository directly as an eclipse project and then tried to copy a folder from another eclipse project into this one.Strangely all those folder files have vanished from local system (and obviously they never made it to SVN repository). </p>
  
  <p>Somehow We have obtained .svn-base files for some CLASS files.Now We are trying to decompile class files to obtain the source code back. However some of the class files are giving error "invalid input file" when jd compiler is trying to process them.
  Is there any other solution to this ?</p>
