title: SDK Manager failed to install 'java.exe' locking directory
body: <p>I have ran into a curious error when trying to update <code>Android SDK Tools</code> to <code>revision 21</code> from <code>revision 20.0.3</code>. The ADT plug-in updated properly so now I am at a stand still until resolved.</p>
  
  <p>The initial error I got listed <code>cmd.exe</code> &amp; <code>java.exe</code> as locking the directory, I forced closed <code>cmd.exe</code> and got this:</p>

  <p>If I force close <code>java.exe</code> then obviously my SDK Manager closes.</p>

  <p>This is my work computer so I'd really like to avoid any down-time resulting from a reboot, just curious if anyone has come across this issue and been able to resolve.</p>
  
  <p>I have tried closing Eclispe and running SDK Manager from the file directory, same issue, I read that someone had experienced this while having the directory opened so I closed and still, same issue. Any help is appreciated.</p>
