FULL PRODUCT VERSION :
java version "1.5.0_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_03-b07)
Java HotSpot(TM) Client VM (build 1.5.0_03-b07, mixed mode, sharing)


ADDITIONAL OS VERSION INFORMATION :
Fedora Linux 2.6.11-1.14_FC3 #1
Redhat Linux 2.4.21-4.ELsmp

EXTRA RELEVANT SYSTEM CONFIGURATION :
X-Window managers tested: KDE 3.3, GNOME 2.8, FVWM 2.4
X-Windows tested: x.org 6.8.2 , XFree86 4.3

A DESCRIPTION OF THE PROBLEM :
Neither the setLocationRelativeTo() in java.awt.Window nor the JDialog is working properly from the bottom screen when a vertically aligned Xinerama configuration is used (e.g. "Screen1" Above "Screen0"). In this case, the pop-up window always goes to the corresponding upper screen instead of near the parent window. It works fine with only horizontally aligned Xinerama or the upper screen(s) of vertical layout. The same source code was tested against JDK 1.4.x and worked perfectly.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Set Xinerama in the XF86Config or xorg.conf as:

Section "ServerLayout"
        Identifier "dual-head configuration"
        Screen 0 "Screen0" 0 0
        Screen 1 "Screen1" Above "Screen0"
        InputDevice "Mouse0" "CorePointer"
        InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Then, try the provided sample running from the lower screen of multi-head display.
i

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The pop-up window should attach to its parent window or near it.
ACTUAL -
The pop-up window goes to top of the upper screen, instead.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
No error message.

REPRODUCIBILITY :
This bug can be reproduced always.
