FULL PRODUCT VERSION :
openjdk version "1.8.0_45-internal"
OpenJDK Runtime Environment (build 1.8.0_45-internal-b14)
OpenJDK 64-Bit Server VM (build 25.45-b02, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Linux 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1 (2015-05-24) x86_64 GNU/Linux

A DESCRIPTION OF THE PROBLEM :
JavaFX controls will slow down considerably when displaying text in RTL languages such as Arabic or Hebrew. This is _not_ an issue with NodeOrientation, only with the actual language text.

Same code with text in English or other non-latin languages (Such as Japanese or Russian for example) work fine.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create a ComboBox (this is probably happening in other controls too, but is most notable in a ComboBox).
2. Add >10 items with text in either Hebrew or Arabic.
3. Try to scroll through the items in the ComboBox.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Opening the ComboBox and scrolling through it should be as fast as when the strings inside are in any other language.
ACTUAL -
Opening and scrolling through items is extremely slow and laggy.

REPRODUCIBILITY :
This bug can be reproduced always.
