> After the upgrade to the latest Tika jar we see a lot of errors like this:
> 2008-03-06 08:07:20,659 WARN org.apache.tika.mime.MimeTypesReader: Invalid media type alias: text/xml
> org.apache.tika.mime.MimeTypeException: Media type alias already exists: text/xml
> 	at org.apache.tika.mime.MimeTypes.addAlias(MimeTypes.java:312)
> 	at org.apache.tika.mime.MimeType.addAlias(MimeType.java:238)
> 	at org.apache.tika.mime.MimeTypesReader.readMimeType(MimeTypesReader.java:168)

> 	at org.apache.nutch.fetcher.Fetcher2$FetcherThread.run(Fetcher2.java:523)
> This is caused most likely by the duplicate tika-mimetypes.xml file - one copy is embedded inside the Tika jar, the other is found in Nutch conf/ directory. The one inside the jar seems to be more recent, so I propose to simply remove the one we have in conf.
