title: Eclipse does not restart in Ubuntu
body: <p>I have Ubuntu 16.04  and Eclipse Oxygen 3.A installed on my machine. The Eclipse restart does not work. Eclipse closes but does not start again neither by 'Restart' menu nor if an application requires a restart.</p>
  
  <p>Update: I cleared <code>.metadata/.log</code> and then restarted Eclipse from the menu. As usual Eclipse closed down but did not start again. I had to start it by clicking on the icon on my taskbar. Below is the logs generated when I started Eclipse.</p>
