Issue #52 wontfix
Caused by: java.lang.IllegalAccessError: tried to access method com.sun.javafx.css.parser.CSSParser.<init>()V from class de.jensd.fx.glyphs.GlyphIcon at de.jensd.fx.glyphs.GlyphIcon.<clinit>(GlyphIcon.java:49)
As said in the title I used snapshot 8.4 like I saw in an earlier issue. My problem was not resolved. I am trying to use the icons from SceneBuilder with fxml file.
