title: Eclipse RCP Progress Monitor not showing anymore
body: <p>I have an Eclipse RCP application that's using ProgressMonitors to provide continuous feedback to the user. All worked fine since a few days ago when suddenly <strong>all</strong> ProgressMonitors used in the application failed to show up. </p>
  
  <pre><code>IProgressMonitor monitor = Job.getJobManager().createProgressGroup()
  Job jobMain = new Job("Initializing ...") {
      @Override 
      protected IStatus run(final IProgressMonitor monitor) {
          monitor.beginTask("doing stuff", 100); 
          // DO STUFF  
          return Status.OK_STATUS; 
      }
  }; 
  jobMain.setUser(true); 
  jobMain.setProgressGroup(monitor, 100); 
  jobMain.schedule(); 
  </code></pre>
  
  <p>Is this an Eclipse issue? Has anyone ever had that problem that <strong>no</strong> Progress Dialogs showed anymore? </p>
