title: Jdeveloper 11gR1: java.lang.IllegalStateException when opening project
body: <p>I installed 11.1.1.5 just now, and am getting this error every time I try to open a project or a directory in a project, I get the following error:</p>
  
  <p>java.lang.IllegalStateException: Timer already cancelled.</p>
  
  <p>And it doesn't display the files.</p>
  
  <p>To exclude any other factors I did a fresh install in a new Ubuntu VM image - same problem.
  I'm really at my wit's end.</p>
