PS as referenced in that bug the updated INTL guide 
https://docs.oracle.com/en/java/javase/25/intl/font-configuration-files.html#GUID-F8ABF748-F3C3-4781-97B2-66C7E1E10EE9
 says

The JDK places any files that it provides in $JDKHOME/lib.
Do not modify that location.
Instead, put any updates or custom versions of the configuration files in 
$JDKHOME/conf/fonts.
On platforms that support font configuration files, the runtime will look first 
in $JDKHOME/conf/fonts.
