title: org.apache.subversion.javahl.ClientException - client is too old
body: <p>I get the following error message when I try to compare files in Eclipse using Subclipse:</p>
  
  <blockquote>
    <p>Unsupported working copy format svn: This client is too old to work with the working copy at 'C:\XXX' (format 31). You need to get a newer Subversion client. For more details, see <a href="http://subversion.apache.org/faq.html#working-copy-format-change" rel="nofollow">http://subversion.apache.org/faq.html#working-copy-format-change</a>.</p>
  </blockquote>
  
  <p>I'm using, svn (command line): 1.8.0, Subclipse: 1.8.22, Subversion JavaHL: 1.7.10.</p>
  
  <p>What could be wrong?</p>
