Before:

if (DB4Utils.MEMO_FIELD_RESERVED_BYTES[0]` != recordHeaderBytes[0] ||
            DB4Utils.MEMO_FIELD_RESERVED_BYTES[1] != recordHeaderBytes[1] ||
            DB4Utils.MEMO_FIELD_RESERVED_BYTES[2] != recordHeaderBytes[2] ||
            DB4Utils.MEMO_FIELD_RESERVED_BYTES[3] != recordHeaderBytes[3]) {

After:

if (BytesUtils.equals(MEMO_FIELD_RESERVED_BYTES, 0, recordHeaderBytes, 0, 4)) {
