Nit: can you use a common final variable here as well?

Review comment:
I generally don't have anything against using lambdas, but this doesn't
seem like an improvement over a simple for or for-each cycle. Performance wise
(doesn't matter too much in this case) it's similar, but this I think is a bit
harder to read, and debugging it is harder (because the unusual stacktrace that
comes from the lambda), and in the future if for some reason someone wants to
throw a checked exception when parsing the config he/she will need to rewrite
this to a for cycle.
