I have a frame, for which i set my own icon through icons attribute which takes the images. The new icon is set as the frame icon. I have a dialog , whose owner is the frame. When the dialog is visible , it has the default Java cup icon, this is incorrect. Dialog should inherit the owner's icon. unless we have specified with different icon. This happens only for javafx.application.Dialog . It works fine for javafx.ext.swing.SwingDialog. I tested this on winxp with b24 reprise promoted build & jdk6u10 b27 promoted biuld. I have attached the screen shot , testcase & images used for this testcase.
