Hi @arey
I fixed the issues you pointed out.

Thank you @alexandre-touret Could you check why code coverage has decreased?

Hi @arey
I just checked and reproduced this issue on my laptop.

It fails now because in the github action definition, it's now

      - name: Build with Maven
        run: mvn -B install --file pom.xml

instead of

      - name: Build with Maven
        run: mvn -B package --file pom.xml

The install step checks the jacoco report and fails the build if the coverage rate is not high enough.

So you have to add some lines of test or decrease the limit of the code coverage.
