<Swing Dev> [14] RFR JDK-8193544:Regression automated test '/open/test/jdk/javax/swing/JDialog/Transparency/TransparencyTest.java' fails

[Prasanta Sadhukhan]

Hi All,

Please review a testbug fix for a test issue seen to be failing 
intermittently in linux nigthly system.

The test iconifies and deiconfies a transparent JDialog and check if it 
retains the opacity. It seems the the color check fails as the 
iconify/deiconify is happening too fast for the slow nightly system.

Introduced some delay which made sure enough time is available for 
iconify/deiconify sequence to finish. Mach5 job as posted in JBS is green.

I have also tested in windows where the 8062946 fix was made and it 
fails without the fix and pass with the fix with the modified test.
