I set this up to analyze all the files I have in my downloads folder to see
what happened and what errors I came across. I found a couple interesting ones.
The first should be a configurable property. The second looks like problems
attempting to extract metadata from JPGs. You can recreate the problem by
setting up a unit test to analyze simple.jpg (in test resources):
org.apache.tika.sax.WriteOutContentHandler$WriteLimitReachedException: Your
document contained more than 100000 characters, and so your requested limit has
been reached. To receive the full text of the document, increase your limit.
(Text up to the limit is however available).
