Bug#912476: libapache-poi-java FTBFS with OpenJDK 11

[Emmanuel Bourg]

Adding JAXB to the classpath isn't enough, the build also fails due to
this upstream bug:

  https://bz.apache.org/bugzilla/show_bug.cgi?id=62187

So we have to upgrade to the version 4.x to fix the compatibility with
Java 11.

I plan to build temporarily with Java 8 and upgrade to the version 3.17
first. That'll allow us to upgrade tika. I'll then proceed to upgrade
POI to the version 4.x.
