Markus Jelsma commented on NUTCH-964:
-------------------------------------
Well, just building the most recent Gora did the trick this time, Nutch trunk
compiles just right with the upgraded Xerces. I'll check the tests and commit
if things are working as they should. Note, the exception itself does not seem
to occur in trunk.

> 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.
