title: Eclipse won't start, log error only says: !SESSION !SESSION
body: <p>today when I tryed to start my eclipse (I´m running Eclipse Oxygen in Windows 10, it works perfectly all this past days) and I got the following error message in  <code>&lt;workspace-directory&gt;\.metadata\.log</code>:</p>
  
  <blockquote>
    <p>SESSION !SESSION !SESSION !SESSION</p>
  </blockquote>
  
  <p>In order to solve my problem I did all of this not having success:</p>
  
  <p>1 - I deleted the .snap file located in the directory <code>&lt;workspace-directory&gt;\.metadata\.plugins\org.eclipse.core.resources</code></p>
  
  <p>2 - I deleted this <code>&lt;workspace-directory&gt;\.metadata\.plugins\org.eclipse.core.resources\.root\[number].tree</code></p>
  
  <p>3 - I tryed to start it from the Command Prompt cleaning it first <code>eclipse.exe --clean</code></p>
  
  <p>Does anyone can help here? Thanks in forehand.</p>
