title: When opening java files in Eclipse Juno, the editor seems to be minimised or hidden
body: <p>I've installed Eclipse Juno SR1 and switched to my old workspace. When I open a java file in the editor, it seems to be minimized (or hidden). The titlebar shows the current file and the outline displays all methods.</p>
  
  <p>This is much as described in the <a href="https://stackoverflow.com/questions/12206348/eclipse-invisible-editor">Eclipse Invisible Editor</a>, however, the suggested solution 'Window > Reset Perspective' does not work for me.</p>
  
  <p>Any ideas on how I can get the editor back in the window?</p>
  
  <p>I have the same problem with previous version of Eclipse Juno (not SR1).</p>
