I am creating a parent-less Window (java.awt.window) and showing it. When the window is shown, an icon is created on the taskbar for this window on SolSparc10/Linux. This is reproducible only since JDK7-b03 and not reproducible on JDK6-FCS.

Not reproducible on Win32. (Icons are created for parent-less dialogs on Win32 as well as SolSparc which I think is expected.)

Run the attached test to reproduce.
