I have a question about the following codes. Doesn't it make the compare method always return EQUAL? It compares same input argument.
```
byte[][] firstBytes = splitKey(first.getByteArray(0));
- byte[][] secondBytes = splitKey(second.getByteArray(0));
+ byte[][] secondBytes = splitKey(first.getByteArray(0));
```
