Can you please add the new PMD support to the release notes (release notes of
20.02)?

Why it is GPL-2.0 licensed?

What is the license of the PMD overall?

Can you please provide a link to the product page to get more detailed information?

Is the allow exprerimental flag really required? If so can you please add the
experimental APIs used as a comment.

We are not using individual library versioning anymore, please drop this.

This makefile looks like copy/paste from somewhere, please don't add these flags
unless they really are needed.

Same here, please don't include anly library that is not really needed.
