Alan, Mandy and Chris,
Thank you for your comments!
I've committed and pushed an update which implements the suggestion from Mandy to get rid of inherited premain/agentmain methods. I also had to fix 3 tests (InheritAgent0100, InheritAgent1000 and InheritAgent1100) which started to fail with this update as they are relying on the inherited premain methods. I've refactored them to negative tests.
