Work Description: lukaszlenart opened a new pull request, #1616:
URL: https://github.com/apache/struts/pull/1616
## Summary
Backport of #1603 to the 6.8.x branch.
- Add serialization/deserialization support for 6 java.time types
(`LocalDate`, `LocalDateTime`, `LocalTime`, `ZonedDateTime`, `OffsetDateTime`,
`Instant`) using ISO-8601 defaults
- Add Calendar deserialization support (was serialize-only)
- `@JSON(format="...")` annotation works for per-field custom formats on all
new types
- Existing `Date`/`Calendar` serialization behavior unchanged
Fixes [WW-4428](https://issues.apache.org/jira/browse/WW-4428)
## Test plan
- [x] Each java.time type serializes to expected ISO format
- [x] Each java.time type deserializes from ISO string
- [x] `@JSON(format="dd/MM/yyyy")` custom format works for serialization and
deserialization
- [x] Calendar deserialization works
- [x] Null value handling for temporal types
- [x] Round-trip test: serialize → deserialize → assert equality (LocalDate,
Instant, ZonedDateTime)
- [x] Custom format for OffsetDateTime serialization and deserialization
- [x] Malformed input throws JSONException
- [x] Existing Date/Calendar tests still pass (regression)
