We encounter problem when using ImageIcon, anyone can help?
In JFrame1, we use ImageIcon to show an image (says, C:\abc.jpg with an apple) on JButton
It shows Apple on the Jbutton.

We then update abc.jpg. (says, copy C:\def.jpg with an orange to C:\abc.jpg)
So, we check in Windows, both abc.jpg and def.jpg are orange now.

But when we load again JFrame1, the image on JButton is still show apple.
We expect it is an orange.

So, we close the apps and start again.
Now, it shows orange.

We use ImageIO.read to read the image to BufferedImage and use it in construct ImageIcon.

It seems that ImageIcon cache the image and does not reload it.
How can we clear the cache and force ImageIcon to load the latest image?

Thank you.
