Resolved Loading css stylesheets

Code (Text):

1.  
2. String alphaCss = Environment.getScript().getClass().getResource("/com/alpha/api/framework/ui/theme/Alpha.css").toExternalForm();
3. System.out.println(alphaCss);scene.getStylesheets().addAll(Themes.getCurrentStylesheet(),  alphaCss);

Works fine locally, throws a NPE on SDN.
css file is added as a resource, works fine locally.

Pls, I just want to make my UIs pretty
