Line 95 : scene.getStylesheets().add("scatterchartsample/Chart.css");

This doesn't make an exception, just warning "WARNING: com.sun.javafx.css.StyleManager loadStylesheet Resource "null" not found." But I think, as this java file is single (without project) this line could be removed.

BTW, file is attached in the project.
