🦉 Deserialization of Untrusted Data

[ib-tjuhasz]

This upgrade to Jackson 2.18.x is a minor version update but introduces significant internal changes that carry a medium risk of causing behavioral shifts, particularly in deserialization.

Key Changes:

• Property Introspection Rewrite: The most significant change in version 2.18.0 is a deep rewrite of the POJO property introspection logic. This was done to fix long-standing bugs related to how properties from constructors (@JsonCreator) and fields/setters are handled.
• @JsonCreator Behavior Change: A direct side-effect of the introspection rewrite is a change in behavior for deserializing objects, especially those with multiple constructors or Kotlin data classes. Code that previously worked by relying on Jackson's implicit constructor discovery may now fail, requiring the explicit use of the @JsonCreator annotation.
• Kotlin 1.7 Support Dropped: Support for Kotlin version 1.7.x has been removed. Projects using Kotlin must be on version 1.8, 1.9, or 2.0.
• ZonedDateTime Serialization Fix: A bug was fixed in version 2.18.3 where @JsonFormat was not being applied to ZonedDateTime under certain configurations. This fix could change the serialized output for users who were unknowingly relying on the previous incorrect behavior.

Recommendation:

Due to the internal rewrite of core deserialization logic, this upgrade requires careful validation. Pay close attention to the deserialization of complex objects, immutable classes (including Java Records), and Kotlin data classes. It is highly recommended to run your application's test suite to catch any regressions related to object mapping.
