A temporary workaround for the above problem is to set the following flag while running TZUpdater -Dtzupdater.forceUseOfVanguard=true Note: This workaround is forcing the use of vanguard bundle to update tzdata. JDK 7u works only with rearguard bundle. Due to this, there might few timezones which will provide the wrong output.
