I would like to apply css to my codename one application, I have downloaded cn1css-ant-task.jar from git hub and put in my lib directory and I applied css to my app, everything is working fine but after some time I got an error.

The exception you are getting from the CSS processor is "unsupported property": Overflow.
Don't use overflow in the CSS used with Codename One. Notice that you can't just get an arbitrary CSS off the internet and use it.
