JaCoCo does produce own reports. Even taking your project as example - in file "coverage.sh" you have "mvn jacoco:prepare-agent test jacoco:report" that results in generation of native JaCoCo report in directory "target/site/jacoco". > I recently refactored some test classes to pull out their common > functionality into an abstract class, from which they now inherit most of > their @Test methods.

After execution of "mvn test" in TestNG report there is no execution of "AesCounterRandomTest256", nor "AesCounterRandomTest128". Absence of execution of tests perfectly explains absence of coverage of corresponding code. I'm guessing they are not considered as tests as their name doesn't end on "Test".
