Managed to successfully install DirectFB (specified *omap* for the video
driver) on the BBB. However when I tried to run the sample JavaFX 8 program
the following errors appeared:
cmd : cd '/home/debian/NetBeans_Projects//JavaFX_Test';
'/home/debian/ejre-1.8.0_fx/bin/java' -Dfile.encoding=UTF-8
-Djavafx.platform=directfb -jar
/home/debian/NetBeans_Projects//JavaFX_Test/dist/JavaFX_Test.jar
