ADDITIONAL SYSTEM INFORMATION :
Windows 10, Java 1.8.0_171

A DESCRIPTION OF THE PROBLEM :
When attempting to add accelerators in a JavaFX MenuItem object so that the user can use the CTRL+N keys to open a new document where the application is configured for German the label beside the MenuItem text shows "CTRL+N" and not "STRG+N". There also does not seem to be a method to allow the developer to manually change the text displayed.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a menu item and set the accelerator with a KeyCombination.keyCombination("CTRL+N").
Set the Locale.setDefault(Locale.German) or Locale.setDefault(Locale.Germany).
Run the application and see that the menu item's accelerator is CTRL+N and not STRG+N as it should be for a German Locale.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I would expect that instead of CTRL+N I would see STRG+N.
ACTUAL -
CTRL+N

CUSTOMER SUBMITTED WORKAROUND :
No workaround available as the methods that allow access to the text are private or protected and cannot be accessed from the main application.
