I followed the Link, but couldn't find anything "Uh-oh"-worthy.

Is the String-variant of it really that "Uh-oh"-ish?
Isn't scanner.useDelimiter( Pattern.compile(",") ) very likely
to be merely a case of pre-mature optimization to the cost of
making the code a bit more complicated? Especially as it isn't
even happening in the innermost loop...

Or did I miss something else?
