      Description

                if (pos + len > count) {
                    len = count - pos;
                }

        Here len can be close to Integer.MAX_VALUE and pos > 0, which can result in negative (pos + len).

        As a result, read() throws inappropriate StringIndexOutOfBoundsException.
