  <p>I search in the web and find this <a href="http://www.hkmconsultingllc.com/blog/oracle/jdeveloper-12c-fails-start-yosemite/" rel="nofollow">link</a> so I follow and delete the <code>&lt;HOME&gt;/.jdeveloper/system12.1.3.0.41.140521.1008/system_cache</code> folder and the folders for 12.2.1 and 12.2.1.1 without success. Any idea?</p>
  
  <p>Thanks in advance!!</p>
