FYI you should embed the stack into the question and not include it as an image and that's not a null pointer exception - Shai Almog

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.
