Test with Array of bytes:

  "diff Arrays of bytes" in {
    case class CaseClassWithArrayBytes(id: String, hash: Option[Array[Byte]])

    import ai.x.diff.DiffShow
    import ai.x.diff.conversions._
    println(
      DiffShow.diff[CaseClassWithArrayBytes](
        CaseClassWithArrayBytes("A", Some( Array[Byte](192.toByte, 168.toByte) )),
        CaseClassWithArrayBytes("B", Some( Array[Byte](192.toByte, 168.toByte) ))
      ).toString
    )

  }

It prints the exception:
