System Preferences Pane for Java fails to open if regional settings are not US (MAC OS X Yosemite)

FULL PRODUCT VERSION :
java version "1.8.0_40"
Java(TM) SE Runtime Environment (build 1.8.0_40-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)


ADDITIONAL OS VERSION INFORMATION :

EXTRA RELEVANT SYSTEM CONFIGURATION :
Region Setting: Serbian (System Preferences > Language & Region > Region)

A DESCRIPTION OF THE PROBLEM :
I clean-installed the latest JDK under OS X Yosemite. The System Preferences pane for Java fails to open.

REGRESSION. Last worked in version 7u65

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Set Region to: Serbian (System Preferences > Language & Region > Region)
2. Try to open Java Preferences Pane (System Preferences > Java). The Java window with message "The Java Control Panel opens in a separate window" should open, but the mentioned window with settings fails to open, showing only "Reopen the Java Control Panel" button.
3. Set Region to: United States (System Preferences > Language & Region > Region)
4. Try to open Java Preferences Pane (System Preferences > Java). Everything works as expected.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expected to see the Java settings window, even with Serbian regional settings in the OS.
ACTUAL -
The settings window fails to open.

REPRODUCIBILITY :
This bug can be reproduced always.
