Ensemble8 has the following code, which use to result in use of fonts from the internet:

When Ensemble8 is starting up, it uses the following code:

   List<String> stylesheets = new ArrayList<>(5);
   ...
   stylesheets.add("http://fonts.googleapis.com/css?family=Bree+Serif");
   ...
   scene.getStylesheets().setAll(stylesheets);

And then in the CSS file, we have entries like:
   .sample-page-box-title {
       -fx-font-family: "Bree Serif";
       -fx-font-size: 16;
       -fx-text-fill: #e1731c;
   }

But we don't seem to pick up the Bree Serif font any more, and we used to.

In addition, we get the following warning:

"com.sun.javafx.css.parser.CSSParser reportException
