Hello,
I have some swing test that I'm running with caciocavallo.
These test are running perfect but in the logs I see the following error.

Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException: sun.awt.peer.cacio.ProxyWindow cannot be cast to be.azvub.util.TAzVubFrame
                at be.azvub.util.TAzVubFrame$WindowAdapter.windowOpened(TAzVubFrame.java:691)

                at java.awt.EventDispatchThread.run(EventDispatchThread.java:97)

The exception occurs in a windowListener where the following code is executed.

public void windowOpened(WindowEvent we) {
         TAzVubFrame azvubframe = (TAzVubFrame) we.getWindow();
         Azvubframe.doSomething();
}

This has no effect on the test because afterwards the method is called again but now we.getWindow() returns the correct window.
The problem is that the window listener is in a package I can't edit. So I can't add a test before the cast.
Mvg,
