Description

This issue changes `bytesHash(data)` API invocation with the underlaying `byteHash(data, arraySeed)` invocation because they are identical.

def bytesHash(data: Array[Byte]): Int = bytesHash(data, arraySeed)

The `byteHash(data)` API is changed between Scala versions by the following commit.
