When I run my program using the css editor on the following css file:

.test {
	background-color_: AliceBlue;
}

I get the following output:

> java CssTest
exception: org.w3c.css.parser.CssParseException: Property background-color_ 
doesn't exist
line: 0

...when it should be line 2.

The program is as follows:

import java.net.MalformedURLException;
import java.net.URL;

import org.w3c.css.css.StyleSheet;
import org.w3c.css.css.StyleSheetOrigin;
import org.w3c.css.css.StyleSheetParser;
import org.w3c.css.parser.CssError;
import org.w3c.css.util.ApplContext;
import org.w3c.css.util.Warning;

public class CssTest {
	public static void main(String[] args) {
		ApplContext ac = new ApplContext("en");
		String fileName = "C:\\Dev\\css-validator\\test.css";
		URL url = null;
		try
		{
			url = new URL("file", "/", fileName);
		}
		catch(MalformedURLException murle)
		{
			murle.printStackTrace();
		}
		String title = "title";
		String kind = "stylesheet";
		String media = null;
			
		StyleSheetParser parser = new StyleSheetParser();
		parser.parseURL(ac, url, title, kind, media, 
StyleSheetOrigin.AUTHOR);
		StyleSheet style = parser.getStyleSheet();
		CssError[] errors = style.getErrors().getErrors();
		Warning[] warnings = style.getWarnings().getWarnings();
		for (int i = 0; i < errors.length; i++) {
			CssError cssError = errors[i];
			System.err.println("error: " + cssError);
		}
	}
}
