Nicholas Roberts updated ARROW-9479:
------------------------------------
Description:
deserializing zero-item tables (as generated by Table.empty or, in this case,
pyarrow.Schema.serialize) with a schema containing a List, FixedList or Map
fail due to an unconditional
{code:java}
new Data(/* preceding parameters */ buffers, [childData]){code}
statement, the childData parameter resolves to [undefined] rather than the
desired [].
See [https://github.com/apache/arrow/pull/7771] for further details.
