Review comment:
Ah, I faced this problem before in spark-xml. I believe you can use
`===` instead, see also https://www.scalactic.org/user_guide/DefaultEquality. I
remember it reports better when the arrays are not equal. e.g.)
```
scala.Predef.intArrayOps(data0).sameElements[Int](scala.Predef.wrapIntArray(scala.Array.apply(1,
2, 3))) was false
```
vs
```
Expected :Array(1, 2, 3)
Actual :Array(-2147417843, -2147393996, -2146420562, -2146408050,
-2145758434, ...
```
