<Swing Dev> [14] RFR JDK-8234332:[TESTBUG] java/awt/Focus/DisposedWindow/DisposeDialogNotActivateOwnerTest/DisposeDialogNotActivateOwnerTest.java fails on linux-x64 nightly

[Prasanta Sadhukhan]

Hi All,

Please review a testbug fix which is failing intermittently in linux-x64 
nightly system

Issue seems like the frame is not getting focus when the frame is 
getitng created and clicked on it. Seems to be a timing issue on slow 
systems as it pass on local systems.

Proposed fix is to add some delay after robot click events.

mach5 job is run with multiple runs on all 3 platforms (link is in JBS) 
and is green.
