[jira] Commented: (NUTCH-964) ERROR conf.Configuration - Failed to
set setXIncludeAware(true)
[ https://issues.apache.org/jira/browse/NUTCH-964?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12987547#action_12987547 ]
Andrzej Bialecki commented on NUTCH-964:
-----------------------------------------
This error has been bothering me for a while, too - it's great that an upgrade fixes it and doesn't break other stuff ;) One area that was sensitive to Xerces versions in the past was the Neko parser (in parse-html) but if its tests pass then +1 to commit the patch. We should upgrade trunk too.

> This can be fixed by upgrading xercesImpl from 2.6.2 to 2.9.1. If modified ivy and lib-xml's ivy configuration and can commit it. The question is, is upgrading the correct method? I've tested Nutch with 2.9.1 and except the lack of the annoying exception everything works as expected.
