> replacement when {{replacement.length() - searchString.length()}} is bigger
> than 134217727 bytes (~132 MB).
> {{public String replace(final String text, String searchString, final String
> replacement, int max) {}}
> {{...}}
> {{final int replLength = searchString.length();}}
> {{int increase = Math.max(replacement.length() - replLength, 0);}}
> {{increase *= max < 0 ? 16 : Math.min(max, 64);}}
> {{final StringBuilder buf = new StringBuilder(text.length() + increase);}}
> {{...}}
