🦉 Allocation of Resources Without Limits or Throttling

[bwappsec]

This is a minor version upgrade for jackson-datatype-jsr310 from 2.17.1 to 2.21.2. The updates consist primarily of bug fixes and feature enhancements.

Behavioral Change:

• A key change in version 2.21 is a bug fix for deserializing negative fractional timestamps. For example, a value like -1.000000001 is now deserialized correctly to 1969-12-31T23:59:58.999999999Z instead of the previous incorrect value. While this corrects a bug, it is a behavioral change that could impact systems relying on the old, incorrect behavior.

Other Changes:

• Version 2.19 included fixes for deserialization, round-tripping, and performance optimizations.
• Version 2.21 introduced the ability to specify a custom DateTimeFormatter for OffsetDateTime serialization and deserialization.

Recommendation:
Verify that your application's handling of negative fractional timestamps is not adversely affected by the bug fix. No other breaking API changes are documented in this range.
