[9] Fix for JDK-8058950 : [TESTBUG] There is no F1 dialog when the case loading, so we can't restore it.

[Ajit Ghaisas]

Hi,

Bug : 
     https://bugs.openjdk.java.net/browse/JDK-8058950

Issue :
    Minimized test frame cannot be restored.

Fix :
   1. The test fix is quite simple - to introduce delay between 
frame.setVisible(true) and frame.setExtendedState(Frame.ICONIFIED).
   2. I have modified test - not to use Applet. This results in multiple 
changes when file diff is seen.

Webrev :

Request you to review.

Regards,
Ajit
