> While reading code for other things I noticed a small inefficiency in the
> splitSmart(String, String, boolean) method where it's creating new
> StringBuilder objects unnecessarily inside a loop. For fun I fixed this and
> JMH bench marked the fix to see what it was worth. The answer is about 30%
> relative improvement, but only a couple microseconds absolute. Not exactly
> exciting since I don't think there's anywhere that really loops hard on this,
> but having it coded and tests passing and improvements measured, might as
> well put it in.
