This is a regression caused by upgrading CLDR to version 39 (JDK-8258794), in which CLDR changed the locale inheritance for Norwegian. Some locale data (including number elements) that were in `nn` locale was moved to `no`. There was a code in CLDRConverter that specially handles `no` locale not to copy its data as parent locale data. That special handling is no longer needed after v39. It's amazing to see this bug has been lurking unnoticed till now.
