ExceptionInInitializerError when String.format() is used in the class loader constructor with locale and language set to English Canada

ADDITIONAL SYSTEM INFORMATION :
Windows 10 and server 12
Java 8

A DESCRIPTION OF THE PROBLEM :
The JVM crash with exception at startup

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
using Windows 10 change the language English US and locale to Canada.
Create classloader and in its constructor make a call to String.format (does not matter the arguments)
set the class loader as the JVM classloader using option -Djava.system.class.loader

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The system should start
ACTUAL -
crash occurs at startup with exception below as long as String.format is used in the class loader constructor with the locale and language set as above
Error occurred during initialization of VM

CUSTOMER SUBMITTED WORKAROUND :
Just do not call String.format in the constructor of the classloader. you can use string concat using + will work !

FREQUENCY : always
