> Windows Java runtime has a mapping file /lib/tzmappings which maps Windows time zones to Java's time zones. The file is generated based on CLDR's windowsZones.xml, but in rare occasions, its update is out of sync with Windows updates. This enhancement is to address those discrepancies for the time being (till CLDR/Windows are in sync). This change will also address zone mapping discrepancies in the update releases where CLDR versions stay the same.
