title: Installed JRE/JDKs are not shown on Eclipse Mars' Execution Environments
body: <p>I've just installed Java EE Eclipse Mars, with a JDK 8u45 x64 and JDK 7u79 x64 JDKs. My <code>eclipse.ini</code> file is pointing the <code>-vm</code> option to my Java 8 JDK Home: <code>C:\ambiente_mars\jdk8u45x64\bin\javaw.exe</code>. </p>
  
  <p>When I started Eclipse and was configuring my environment I started to set my <code>Installed JREs</code> like this (and like I've done since Indigo):</p>

  <p>My Compiler Settings are configured this way:</p>

  <p>After all this, I went to <code>Execution Environments</code> to choose the right VM for all the environments, but my configured JRE's are not there:</p>

  <p>Actually, this JRE is not shown for any of the Execution Enviroments &lt;= JSE 1.7. This very same screen, but now on Luna shows everything right, so I think I'm not doing anything wrong.</p>
  
  <p>Maybe this is a bug? Can someone point another way to do it?</p>
  
  <p>Thanks a lot in advance, lads!</p>
  
  <p><strong>Edit 1:</strong> Eclipse is x64 too. Thought it would be good to remember ;)</p>
