A DESCRIPTION OF THE PROBLEM :
The decimal separator for fr_CH is "." and the group separator is "'", but sun.text.resources.ext.FormatData_fr_CH specifies the wrong where sun.text.resources.ext.FormatData_fr_CH provides it correctly.


REGRESSION : Last worked in version 8u241

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Start the example without specification of "java.locale.providers" produces the output "12 500,5" which is wrong.
Start the example with "-Djava.locale.providers=COMPAT,CLDR" produces the output "12'500.5" which is correct.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
12'500.5
ACTUAL -
12 500,5

CUSTOMER SUBMITTED WORKAROUND :
