回答1:

This usually occurs when you use the wrong jdk and jfoenix combination (eg : using jdk8 with jfoenix 9 or jdk9 with jfoenix) To prevent this, if you are using jdk 8, please use the jfoenix library , or jdk 9 with jfoenix for java 9 from here :

Download JFoenix

It will most likely fix your error

Perform these steps in order:

1) Remove the current JFoenix lib jar from SceneBuilder and from Eclipse/ InteliJ / NetBeans.

2) Download JFoenix for Java 8 and add it to SceneBuilder and your IDE. You can download the JFoenix Java 8 file from here: JFoenix Java 8 JAR file
