E.g. maven 3.8.1 behaves slightly better than 3.8.4. But I have to do this kind of changes in several pom files until I get the build to go through.

My version is 3.8.4 which is the current version of maven. But it works for me with JDK 11. So the culprit (in my opinion) is the p2-maven-plugin, which is the only other thing I changed besides the JDK version, or of course, the JDK itself, but this seems to be unlikely.
