The checkstyle failures are weird. Here's a fix of a failure:
https://github.com/apache/tika/commit/50a03d85835405338d47e29fb453c8bc274eac79
It makes the code worse IMHO. What's even more difficult is that
checkstyle doesn't report where the error is. There is a report in the
"site" directory but that one has hundreds of failures.
I tried to make changes in the config in the pom.xml but failed. I
didn't want to spend more time on this so I committed by changes slowly
(which is a habit of mine anyway) to see which file would fail.
