<Swing Dev> [9] Review Request for 6866751:

[Semyon Sadetsky]

Hello,

Please review fix for JDK9:

bug: https://bugs.openjdk.java.net/browse/JDK-7072653
webrev: http://cr.openjdk.java.net/~ssadetsky/7072653/webrev.00/

*THE ROOT CAUSE
Incorrect bounds calculation of heavy weight popup window in the 
BasicComboPopup when the requested popup menu height exceeds screen height.
Additional issue found: popup border thickness is not taken into account 
when popup direction switched to up as the result popup overlaps its 
combo-box by 2 pixels.
Also in multi-monitor desktop if screen are arranged vertically popup 
can be shown on another monitor.

*SOLUTION
The popup location algorithm is corrected to take into account the 
current screen height and border insets.

*TESTING
Test is added to ensure popup window height when combo-box contains 1000 
items.
