Review comment:
       For now, runInternal() seems to catch all exceptions, yes. And we can 
leave it like that.
   In the parent run() method, I suggest:
   try {
      runInternal()
   } finally {
      update metrics
   }
   
   This will protect against any changes inside the runInternal logic that may 
choose to bubble up exceptions or if there is some uncaught exception by 
mistake.
