JDialog moves down in Ubuntu Unity

[bastiK]

If you open a dialog box (e.g. download dialog) the position and size should be restored to the previous values.
However on my system, the box has moved down 28 pixels each time it is opened.

This seems to be caused by a Java or Unity bug:

If you set dlg.setLocation(300,400); and later run dlg.getLocation() or dlg.getLocationOnScreen(), then the result should be (300,400), but in fact it is (301,428).

and

output of test case:

dlg.getLocationOnScreen()=java.awt.Point[x=300,y=400]
dlg.getLocationOnScreen()=java.awt.Point[x=301,y=428]

Shouldn't it be reported to Ubuntu ?

Sure, just reported here: ​https://bugs.launchpad.net/ubuntu/+bug/1110138

Maybe we can find a workaround in the meantime, because it's quite annoying. :)

Thanks. I have added JOMS and myself as impacted project/user, it increases the bug heat :)

Replying to Don-vip:

Thanks. I have added JOSM and myself as impacted project/user, it increases the bug heat :)

Thanks to you too, it seems to have worked. (That and assigning it to the correct project. :) )
Closing this ticket because upstream bugfix is on the way.

[Don-vip]
