Description
FileDialog.getLocationOnScreen throws NPE on Win. Simple test attached. Issue is reproducible on JDK 7 b120, JDK1.6.0_22 on Win7, WinXP.

Test output:
java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode, sharing)
Exception in thread "main" java.lang.NullPointerException: null pData
        at sun.awt.windows.WComponentPeer.getLocationOnScreen(Native Method)
        at java.awt.Component.getLocationOnScreen_NoTreeLock(Component.java:1939)
        at java.awt.Component.getLocationOnScreen(Component.java:1917)
        at FileDialogTest.main(FileDialogTest.java:30)

On Solaris and OEL5.5 that method works, but returns wrong value.
