BREAKING CHANGE

Two changes for "internal fields" (fields within ListTypes and MapTypes):

  • ListType and MapType internal field names only matter in comparisons when check_metadata is true.
  • Nullability of MapType internal fields now matters in comparison.

Seems like the Java test changes won't work as the latest stable PyArrow is used?

I'm pretty sure it uses local PyArrow. I got the tests passing in the other PR. I think the error is just that I added check_metadata to DataType.equals not Array.equals.
