[QF-Test] Problem with Swing lockup

Hi all,
 
I thought I had modified my test application to use SwingUtilities.invokeAndWait() when creating its JFrame but I am still seeing a lockup when it is launched from QFTest.
 
 TestHCIMain(String[] args)
 {
  try {
   javax.swing.SwingUtilities.invokeAndWait( new Runnable() {
    public void run() {
     jFrame = getJFrame();
    }
   } );
  }
...
 public static void main(String[] args)
 {
  System.out.println("TestHCIMain started");
  
  for(int i = 0; i < args.length; ++i)
  {
   System.out.println(args[i]);
  }
  new TestHCIMain(args);
 }
...
 
This gives me a thread dump with the usual Swing thread safety culprit: java.awt.Component$AWTTreeLock
 
It looks like my invokeAndWait call has been triggered on a QFTest thread:

Anyone seem anything obvious I've missed?
