Consider sm\trace\watch command support inherited methods?

Template method is common used in java system.
Such as:


There may be many different handlers. Now we can't trace one sub-handler, like:
`trace demo.MyHandler handle`

Consider to support this feature?

Start by locating the implementation of the sm\trace\watch command and how it resolves handler methods. Reproduce the reported case with a subclass and inherited handle method, then inspect existing trace behavior. Done means tracing the selected sub-handler works when the method is inherited, with coverage for the demonstrated scenario.
