I have installed JDK 8 from http://www.oracle.com/technetwork/java/javase/downloads/index.html
java -version
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)
System Version: OS X 10.11.2 (15C50)
After lots of googling I couldn't find a way to start Java FX scene Builder
Any help is appreciated.
