Jukka Zitting resolved TIKA-239.
--------------------------------

    Resolution: Cannot Reproduce

Not sure what we've changed related to this, but I can no longer reproduce this problem with Tika 0.6.

> The XmlRootExtractor is often given non-XML files to look at, which causes the XML parser to fail with error messages. It looks like the default behaviour is to print some of these error messages to System.err, as shown below:
