[QF-Test] Problem with Swing lockup

  • Subject: [QF-Test] Problem with Swing lockup
  • From: STEPHENS Patrick <patrick.stephens@?.com>

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)
  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:
 at com.thalesgroup.sat.toolbar.test.TestHCIMain.getJFrame(TestHCIMain.java:122)
 at com.thalesgroup.sat.toolbar.test.TestHCIMain.access$100(TestHCIMain.java:45)

Anyone seem anything obvious I've missed?
