> Prior this change we won't use use native crc32 checksum verification as in 
> DataChecksum#verifyChunkedSums we would go this codepath
> if (data.hasArray() && checksums.hasArray()) {
>   non-native checksum
> }
> So we were fine. However, now we're dropping below and try to use native crc32 is one's
available (and I think it's not in the tests), which expect DirectByteBuffer.
