Chris A. Mattmann commented on NUTCH-618:
-----------------------------------------
Dennis Kubes tested this patch for me. According to Dennis, there were 2
lingering log warnings that still came up:
1. For alias:
<alias type="application/x-dosexec;exe" />
removing the ;exe removed one of the errors
2. removing the subclass from:
<mime-type type="application/xhtml+xml">
<sub-class-of type="text/xml" />
<glob pattern="*.xhtml" />
<root-XML namespaceURI='http://www.w3.org/1999/xhtml'
localName='html' />
</mime-type>
removes the second of the errors.
I am going to attach an updated patch that address these issues.
Thanks,
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.
