    Attachment: NUTCH-618.Mattmann.patch.060108.txt

Hey Guys:

Okey dok: here's a candidate patch. Could someone who has an environment set up already in which these types of errors were manifesting please trying this patch out and see if it makes them go away? I'm thinking that the root of the issue is that the MimeTypes object was not necessarily being re instantiated many many times as much as it wasn't being cached in the ObjectCache. We'll see.

This attached patch passes all unit tests. So, please let me know what you think.

Thanks!

Cheers,
 Chris

> After the upgrade to the latest Tika jar we see a lot of errors like this:

> 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.
