No transparency in Vista JFrame icon

Frame and JFrame's SetIconImage() does not respect transparency in Vista
when using a JVM prior to 1.6.

Any ideas on possible alternatives (other than drawing the entire frame
myself)?

BTW, I can't upgrade to 1.6 because:
The application has already been downloaded to many customers using an
older (pre-1.5) JVM.
Many versions of the program are still burned on CDs on store shelves.
We use an autoupdater that doesn't support replacing the JVM.

Doesn't it? What about XP running 1.5?
(Is it Java, or Windows?)

PNG with transparency?

Thanks for replying.

The icon transparency works fine on XP using 1.4.2.x, 1.5, and 1.6.

I am using a PNG file. I tried using a GIF and even building the image
using the ImageIO library (as opposed to the usual ImageIcon.getImage()
method I previously used), but nothing seems to help.
