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

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
