Summary: java: Component#getLocationOnScreen returning incorrect
coords
Product: Wine

Here's a short java program that behaves correctly on linux and windows, but
not under wine. The program exercises a small part of the java awt toolkit.
1. Create a file with the following contents:
import java.awt.Component;
import java.awt.Container;
import java.awt.Frame;
import java.awt.Point;
public class Bug {
public static void main(String[] args) {
Frame f = new Frame();
Container cont = new Container();
Component comp = new Component(){};
f.add(cont);
cont.add(comp);
f.setSize(100, 100);
f.setVisible(true);
cont.setBounds(10, 10, 80, 80);
comp.setBounds(10, 10, 60, 60);
Point frameLoc = f.getLocationOnScreen();
Point compLoc = comp.getLocationOnScreen();
// The component now should have
// (frameLoc.x + 20 + i.left, frameLoc.y + 20 + i.top).
System.out.printf("a.x=%d, a.y=%d / b.x=%d, b.y=%d\n",
compLoc.x, compLoc.y, frameLoc.x, frameLoc.y);
f.dispose();
}
}
2. Compile it:
javac Bug.java
3. Download a JDK from java.sun.com and install it in Wine
4. Use it to run Bug.class, e.g.
cd '.wine/drive_c/Program Files/Java/jre1.6.0_01'
cp ~/Bug.class .
wine bin/java.exe Bug
5. Returns inconsistent results under wine. Under linux and windows it
consistently returns "a.x=20, a.y=20 / b.x=0, b.y=0". Occasionally wine returns
correct results, but repeated invocations of the application should produce
inconsistent results (e.g. "a.x=16, a.y=-3 / b.x=-4, b.y=-23").
