I wonder, shouldn't it be (n <= k) here:

 164             long k = count - pos;
 165             if (n < k) {
 166                 k = (n <= 0) ? 0 : n;
 167             }
 168             pos += k;
 169             return k;

"k" is the max number of chars to skip. It should be possible to skip
all remaining chars when (n == k), right?

Thanks,
