Here is a minimal code snippet which reproduces the crash: > {code:java} > import pyarrow as pa > from pyarrow import parquet as pq > array = pa.array([[]], type=pa.list_(pa.int32())) > table = pa.Table.from_arrays([array], ["A"]) > pq.write_table(table, "tmp.parq"){code} > When the ListArray has at least one non-empty list, the issue disappears. > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
