title: Eclipse photon always resets key bindings on restart
body: <p>I do use Eclipse IDE for Java already for a long time and never something like that happened yet. My issue for now is that I customized some key bindings, but when I close Eclipse for any reason, the key binding settings are resetted and I need to customize it again. </p>
  
  <p>here is the version information: </p>
  
  <blockquote>
    <p>Eclipse Java EE IDE for Web Developers <br>
    Version: Photon Release (4.8.0)
    <br> Build id: 20180619-1200</p>
