NPE when using UIUtil on linux

hi.
when initializing on linux (this is on ubuntu in a VM with oracle java 1.8.0_121) initSystemFontData() in UIUtil.java line 254 throws a NPE because font is null.
getLabelFont() returns null.
(UIUtil.initSystemFontData() gets called because the System property "hidpi" is not set. looking into JBUI.java:47 it sets the scaleFactor = 1.0f; if hidpi != null and not "true")
a workaround is to set hidpi=false and avoid the call to initSystemFontData() alltogether.
the real question is: why does getLabelFont() return null?
using this test application:
import javax.swing.*;
public class Darculatest
{
public static void main(String[] args) {
System.out.println("setting look and feel");
try {
UIManager.setLookAndFeel("com.bulenkov.darcula.DarculaLaf");
} catch (Exception e) {
e.printStackTrace();
}
}
}
throws this exceptions:
setting look and feel

I'm having this same issue, I found workaround by calling javax.swing.UIManager.getFont("Label.font");
before setting the L&F
