Refs #144 (comment)

Following this checklist to help us incorporate your
contribution quickly and easily:

• Make sure there is a JIRA issue filed
  for the change (usually before you start working on it). Trivial changes like typos do not
  require a JIRA issue. Your pull request should address just this issue, without
  pulling in other changes.
• Each commit in the pull request should have a meaningful subject line and body.
• Format the pull request title like [MPMD-XXX] - Subject of the JIRA Ticket,
  where you replace MPMD-XXX with the appropriate JIRA issue. Best practice
  is to use the JIRA issue title in the pull request title and in the first line of the
  commit message.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Run mvn clean verify to make sure basic checks pass. A more thorough check will
  be performed on your pull request automatically.
• You have run the integration tests successfully (mvn -Prun-its clean verify).

If your pull request is about ~20 lines of code you don't need to sign an
Individual Contributor License Agreement if you are unsure
please ask on the developers list.

To make clear that you license your contribution under
the Apache License Version 2.0, January 2004
you have to acknowledge this by using the following check-box.

• I hereby declare this contribution to be licenced under the Apache License Version 2.0, January 2004

• In any other case, please file an Apache Individual Contributor License Agreement.

@adangel thanks for the rework, will review again.

All clean for me, good to merge. Thank you for your patience! I can already see that the code can be a bit simplified with Doxia 2.0.0, but that is a separate topic. Please go ahead and complete this change. I will take care of the next release.

[adangel]

Thank you as well!

I will take care of the next release.

Just for this fix I don't think a new release is needed immediately. It's sufficient, if this lands in the next release whenever it happens.

True, swallowing exceptions is not good and I need to bump to Maven 3.6.3 anyway.
