I have created a single application with HTMLEditor.
I have entered several lines of text and when i am getting out of bounds scroll bar appears, however some visual remains are visible on the scrollbar panel, please have a look at attached images.
appears - when i got out of bound
appearsPlusOne - one more line to the original "appears"
appearsPlusTwo - one more line to the original "appearsPlusOne"
appearBackOne - removed one line from the original "appearsPlusTwo"

I am using http://jfx.us.oracle.com/hudson/view/2.2/job/2.2/label=windows-i586-14/80/

to run:
1. javac -cp ./rt/lib/jfxrt.jar pathToFile\ScrollBarIssueApp.java
2. java -Dcom.sun.javafx.isEmbedded=true -cp ./rt/lib/jfxrt.jar;pathToFile ScrollBarIssueApp
