关于#stringbuilder#的问题，如何解决？

String的最大长度是65535
StringBuilder最大长度是多少?

private void ensureCapacityInternal(int minimumCapacity) {
　　// overflow-conscious code
　　　　if (minimumCapacity - value.length > 0)
　　　　　　expandCapacity(minimumCapacity);
　　}

void expandCapacity(int minimumCapacity) {
        int newCapacity = value.length * 2 + 2;
        if (newCapacity - minimumCapacity < 0)
            newCapacity = minimumCapacity;
        if (newCapacity < 0) {
            if (minimumCapacity < 0) // overflow
                throw new OutOfMemoryError();
            newCapacity = Integer.MAX_VALUE;
        }
        value = Arrays.copyOf(value, newCapacity);
    }

StringBuilder 长度是 int 的最大值 2^32大约等于21亿.
