Arrow Java API Changes

This document tracks behavior changes to Java APIs, as listed below.

    • Start date: 2019/07/18
    • Resolve date: 2019/07/20
    • Brief description: The semantics of the get methods for VarCharVector, VarBinaryVector, and FixedSizeBinaryVector changes. In the past, if the validity bit is clear, the methods throw throws an IllegalStateException when NULL_CHECKING_ENABLED is set, or returns an empty object when the flag is not set. Now, the get methods return a null if the validity bit is clear.
