>
> While investigating a test failure in {{TestRecoverStripedFile}}, one issue
> in raw erasrue coder, caused by an optimization in below codes. It assumes
> the heap buffer backed by the bytes array available for reading or writing
> always starts with zero and takes the whole space.
> {code}
> protected static byte[][] toArrays(ByteBuffer[] buffers) {
> byte[][] bytesArr = new byte[buffers.length][];
> ByteBuffer buffer;
> for (int i = 0; i < buffers.length; i++) {
> buffer = buffers[i];
> if (buffer == null) {
> bytesArr[i] = null;
> continue;
> }
> if (buffer.hasArray()) {
> bytesArr[i] = buffer.array();
> } else {
> throw new IllegalArgumentException("Invalid ByteBuffer passed, " +
> "expecting heap buffer");
> }
> }
> return bytesArr;
> }
> {code}
