A more informative message and an earlier detection both sound good. Not
sure about the pointer to the Wiki page, though. We haven't done that in
the past that I am aware of. If we do want to go down that path, I would
suggest a pointer to a single, "well-known" support page that could
describe various end-user configuration issues that we might want to
document.

I say blame it on CSS because the resulting hard failure is:
Exception in thread "JavaFX Application Thread"
java.lang.NoClassDefFoundError: Could not initialize class
javafx.scene.CssStyleHelper
This is because CSS needs a font for various calculations.
With Embedded, if libfontconfig is not present (or improperly
configured) you will not find any fonts.
I would like thoughts on my putting a more informative error message
out, and making zero fonts an earlier hard failure.
What I would really like to do is to be able to put a URL to a Fonts
wiki page (like:
https://wiki.openjdk.java.net/display/OpenJFX/Font+Setup) but not sure
how well that would stand up to the test of time.
The code point in FontConfigManager is:
if (anyFont == null) {
if (debugFonts) {
System.err.println("Fontconfig returned no fonts at
all.");
}
fontConfigFailed = true;
return;
