Fix unparseable pom.xml: -- is not allowed inside an XML comment

The previous commit put "-- which is how" inside a <!-- --> block, which XML
forbids, so pom.xml stopped parsing and all three CI jobs failed, Linux
included.

It was pushed because the local check could not see it. The verification was

    mvn -q clean test 2>&1 | grep -E "^Tests run:|BUILD FAIL" | tail -1

and the actual error is "Non-parseable POM", which matches neither pattern. The
grep printed nothing, and nothing read as success. A filter that silently passes
on an unmatched failure is not a check. Verified here on the exit code instead,
with the POMs and the workflow YAML parsed explicitly.

mvn clean package -DskipTests: exit 0.
mvn clean test: 144 tests, the same 3 known analyzespTest failures.
