> {code:java|title=NonSyncByteArrayOutputStream}
> private int enLargeBuffer(int increment) {
> int temp = count + increment;
> int newLen = temp;
> if (temp > buf.length) {
> if ((buf.length << 1) > temp) {
> newLen = buf.length << 1;
> }
> byte newbuf[] = new byte[newLen];
> System.arraycopy(buf, 0, newbuf, 0, count);
> buf = newbuf;
> }
> return newLen;

> {code}
> This will fail if the array is 2GB or larger because it will double the size
> every time without consideration for the 4GB limit on arrays.
