title: Can not open Eclipse IDE after update form Luna to Mars
body: <p>I updated eclipse Luna to Mars.
  What I did is ...</p>
  
  <ul>
  <li>Add mars url to <code>Window &gt; Preferences &gt; Install/Update &gt; Available Software Sites</code></li>
  <li><code>Help &gt; Check for Updates</code></li>
  <li>Followed what the wizard indicated</li>
  <li>Installed successfully and a pop up showed that I have to reopen this application(Eclipse)</li>
  </ul>
  
  <p>And now, when I trying to open eclipse, A pop up message shows. It said "Can not open this application" and no other any Informations.</p>
  
  <p>It seems like update successfully, so I do not have any idea what is wrong is it. How can I fix or got some clues about this situation? 
  Thanks</p>
  
  <p>FYI, I attach my <code>eclipse.ini</code> and result of <code>java -version</code>.</p>
  
  <p>This is ini file</p>
