Description
The plugin urlfilter-validator rejects URLs with an IPv6 address as hostname/authority (given according to RFC 2732:
% echo "http://[2010:836B:4179::836B:4179]/" \ | bin/nutch filterchecker -filterName urlfilter-validator -stdin Checking combination of these URLFilters: UrlValidator -http://[2010:836B:4179::836B:4179]/
We should also consider to use the class UrlValidator from commons-validator directly instead of a modified copy. This would help to get updates and improvements with little effort - IPv6 is already supported, see the class implementation.
