When I try to create scene including ColorPicker, it gives runtime error. I detected this is because locale. I am using Turkish locale and if I add "Locale.setDefault(Locale.ROOT);" command before creating scene, it is resolved.

Same issue (including other classes) is fixed in openjdk here: http://hg.openjdk.java.net/openjfx/8/master/rt/rev/16d1fc60bd6a

Here is my exception:
