> StringUtils.equals(cs1,cs2) delegates to CharSequence.regionMatches(...) in a
> way that causes IndexOutOfBounds when either of cs1/cs2 isn't a String.
> Specifically, comparing "foo" and "foobar" for non-String CharSequences bombs
> due to CharSequenceUtils.regionMatches(cs1, false, 0, cs2, 0,
> Math.max(cs1.length(), cs2.length())) because regionMatches doesn't check for
> input exhaustion.
