Undecorated JDialog border

Solution
You need to change the `Border` of the root pane:
getRootPane().
setBorder( BorderFactory.createLineBorder(Color.RED) );
Problem
I have a question regarding the border around an undecorated `JDialog` using the `Metal L&F`. Look at this picture to see the border that is on this window: I'm trying to figure out how to either get rid of or change the color of the blue border around the very outside of the `JDialog`. I looked at the UI defaults for the `Look & Feel` but I wasn't able to come up with any that worked for this. Does anybody have any ideas on how to get rid of that border? Thanks!
