<Swing Dev> <AWT Dev> [9] Review request for 8171808: Performance problems in dialogs with large tables when JAB activated

[Sergey Bylokhov]

Hi, Mikhail
Why we call invokeAndWait() so many times in the new method?
I guess we can do some work on EDT in one step then we will speedup the code when the size of the table is huge and it has lots of visible items.
