Yeah, I saw there's a mismatch between the src and limit in this call that led
to the index check Exception:
286 for (int b = ci.getBeginIndex(); b < end;) {
287 boundaries.add(b);
288 b = Grapheme.nextBoundary(text, b, end);
289 }
and nextBoundary could walk through the entire CharSequence. Maybe it's worth a
note to the length() method.
