JDK 1.6 and JFrame icon

Thread view:

Hello,

I'm testing my application using JDK 1.6 (to make sure it will also work
with that).

There is one thing that is not working properly: my icon that I set for
the main window (JFrame) is not displaying under Windows when using
Alt-Tab. I does display fine in the window itself and in the task bar,
but not when I use Alt-Tab.

Any idea? Maybe a know bug in JDK 1.6 (I have noticed this with NetBeans
as well, so it seems to be related to the JDK and not necessarily to my
program)

Thanks in advance
Thomas

Maybe a bug related to the new 1.6 feature which allows you to specify
multiple icon images. The platform chooses the best image where needed,
e.g. a 16x16 image as title bar icon, and a 32x32 one as Alt-Tab icon

il.List)>

I broke it down to a reproducable test case now. It does seem to be a
bug in 1.6 When using setIconImage() everything seems fine until you
open a modal dialog (e.g. a JFileChooser). After that the frame icon
will revert back to the default Java icon
