Review request for 7125044 - [macosx] Test failure because Component.transferFocus() works differently in applet and application.

[Artem Ananiev]

Hi, Anton,

the webrev looks fine. As a possible optimization, you can try to 
combine the two tests into a single one with several @run tags, but I'm 
leaving it up to you :)

Thanks,

Artem
