Coleen, I think the bug can be caused only by executing the "classes" command of CLHSDB since the code is for registering the command. So I don’t know how to test it other than executing the command itself and I don’t find such kind of test that executes CLHSDB commands in current test code(not sure about that and hope someone in Serviceability team could confirm).

We didn't test the serviceability agent that thorougly, except for our automated tests. Should there be a test that we can add with this patch?
