Hi devs, taking a look at KStreamPrintTest I can't find any substantial difference between the two tests :
testPrintStreamWithProvidedKeyValueMapper testPrintKeyValueWithName The only tiny difference is the mapper output "%d, %s" instead of "(%d, %s)" but then all the code seems to be the same (some other "final" missing ...). Is there something that my eyes can't see ?
