Migrate to Jackson 3.2.1 by alexander-yevsyukov · Pull Request #955 · SpineEventEngine/base-libraries

alexander-yevsyukov · 2026-08-08T00:06:11Z

Migrates the repository from Jackson 2.22.1 (com.fasterxml.jackson) to Jackson 3.2.1 (tools.jackson), following the Jackson 3 migration brief (config/docs/jackson-3-migration-brief.md).

What changed

The config submodule points at its bump-jackson tip, and buildSrc is synced from it: the Jackson dependency object now serves tools.jackson:jackson-bom:3.2.1 — confirmed the newest 3.2.x. jackson-annotations deliberately stays on 2.x (BOM-resolved to 2.22), the only com.fasterxml artifact on the runtime classpath.
The format module is migrated to the tools.jackson.* packages and Jackson 3's immutable mappers: JacksonSupport abstracts over a MapperBuilder (JsonMapper.builder() / YAMLMapper.builder()) instead of a shared JsonFactory; parsers keep sharing the writers' mapper configuration. The jackson-datatype-jdk8 and -jsr310 dependencies are removed — both merged into jackson-databind in 3.x.
Jackson module discovery is ServiceLoader-only via MapperBuilder.findAndAddModules(). The public mutable JacksonSupport.modules list is removed; modules are contributed by exposing them as services, e.g., with @AutoService(JacksonModule::class).
@throws documentation is corrected: Jackson 3 throws the unchecked JacksonException (and subclasses) instead of IOException; IOException remains accurate for file reading and the Protobuf-backed formats.
Version: 2.0.0-SNAPSHOT.426 -> 2.0.0-SNAPSHOT.430 (breaking-change rounding per the version policy).

Wire format

The only serialization change vs. 2.22.1, established by byte-diffing outputs of the same value: java.time types are now written as ISO-8601 strings instead of numeric epoch values (DateTimeFeature.WRITE_DATES_AS_TIMESTAMPS is off by default in 3.x). Property order for Kotlin data classes is unchanged (constructor properties keep declaration order), and YAML output is otherwise byte-identical despite the switch to snakeyaml-engine. Fixtures generated under 2.22.1 are committed as test resources, and Jackson2CompatibilitySpec proves they still parse correctly under 3.2.1. All 3.x changed defaults are accepted (none restored); the decision log lives in .agents/tasks/bump-jackson.md.

Breaking changes

JacksonSupport.Companion.modules (MutableList<Module>) is removed.
Jackson types visible in the format API move from com.fasterxml.jackson.* to tools.jackson.*.

Reviewer notes

Depends on the config repository's bump-jackson branch (the submodule is pinned at its tip).
buildSrc keeps its own Jackson at 2.18.3 deliberately: buildSrc sources still use the 2.x API; the decoupling comment comes from config.
Pre-PR gate: ./gradlew build dokkaGenerate green; spine-code-review, kotlin-engineer, and review-docs all returned APPROVE. Three cosmetic nits were reported and deliberately left for review: a double "other" in one JacksonSupport KDoc sentence, a repeated [Format] link in the class doc, and the unnamed origin of the @AutoService annotation in an example.

Advance the `config` submodule to its `bump-jackson` tip, which migrates the `Jackson` dependency object to `tools.jackson:jackson-bom:3.2.1` (Jackson 3 group IDs; `jackson-annotations` deliberately stays on 2.x), and copy the resulting `buildSrc` delta into this repository. Also add the task plan for the migration. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Serialize a deterministic `UserAccount` through `io.spine.format.write` while the module is still on Jackson 2.22.1, and store the JSON and YAML outputs as test resources. After the migration to Jackson 3, round-trip tests parse these files to prove that data written by 2.x remains readable. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Move Jackson imports to the `tools.jackson.*` packages and adapt to the immutable mapper design of Jackson 3: - `JacksonSupport` now abstracts over a `MapperBuilder` instead of a `JsonFactory`: mappers cannot be configured after construction, so subclasses supply `JsonMapper.builder()` / `YAMLMapper.builder()`, and the base class registers shared modules and enables `INDENT_OUTPUT` on the builder before `build()`. - The shared `modules` list holds `JacksonModule`s (renamed from `Module` in 3.x) and is discovered via `MapperBuilder.findModules()` (the `ObjectMapper.findModules()` static is gone). - Parsers keep sharing the writers' mapper configuration, now via `mapperBuilder()` instead of a shared factory instance. - Drop the `jackson-datatype-jdk8` and `jackson-datatype-jsr310` dependencies: both are merged into `jackson-databind` in 3.x. - Correct `@throws` documentation: Jackson 3 throws the unchecked `JacksonException` instead of `IOException` subclasses; plain I/O failures and Protobuf-backed parsing still surface `IOException`.

Add `Jackson2CompatibilitySpec`, which parses the JSON and YAML fixtures produced by Jackson 2.22.1 and asserts the values are read intact under Jackson 3.2.1, covering `java.time.Instant` (numeric epoch form), Guava collections, and JDK `Optional`. The only wire-format change of the migration, verified by diffing 2.x and 3.x outputs of the same value: `Instant` is now written as an ISO-8601 string instead of a numeric epoch value (`DateTimeFeature`, ex-`WRITE_DATES_AS_TIMESTAMPS`, is now disabled by default). Numeric values written by 2.x remain parseable, as these tests demonstrate. Property order is unchanged: constructor-bound Kotlin properties keep declaration order in Jackson 3.

Regenerated by `build` after the move to `tools.jackson` 3.2.1 coordinates and the removal of the `jdk8` and `jsr310` datatype modules, which Jackson 3 merged into `jackson-databind`. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Add a team-memory note about the silent `*Test`/`*Spec` class-name filter of the shared `test` task, discovered while generating the Jackson 2 fixtures. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Extend the `@throws tools.jackson.core.JacksonException` tags with "or its subclass" — Jackson 3 throws concrete subtypes such as `StreamReadException` and `DatabindException` — matching the phrasing of the neighboring `IOException` tags. In `Jackson2CompatibilitySpec`, backtick the `@DisplayName` subject as sibling specs do, load fixtures via `Class.getResource`, and reflow a widow line in the class KDoc. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Drop the mutable shared module list from `JacksonSupport`: mappers now call `MapperBuilder.findAndAddModules()`, so modules are contributed by exposing them as `ServiceLoader` services (e.g., via `@AutoService`) instead of mutating a public list. This removes the companion object — and with it the registration-timing and concurrent-modification hazards of the former API. Removing the published `modules` property is a breaking change covered by the version bump to `2.0.0-SNAPSHOT.430`. Also apply review feedback to the KDoc: state that new formats are added within the Spine SDK (the `Format` hierarchy is sealed), fix the sentence wrongly attributing other formats to `YAMLMapper`, and note that `java.time` values are now written as ISO-8601 strings while data written by Jackson 2 remains readable.

Pull request overview

Migrates the repository’s Jackson usage from Jackson 2.x (com.fasterxml.jackson.*) to Jackson 3.2.1 (tools.jackson.*), focusing on the format module’s JSON/YAML I/O implementation and updating generated dependency reports and versioning to reflect the breaking API change.

Changes:

Migrated format JSON/YAML parsing/writing to Jackson 3’s tools.jackson.* packages using immutable mapper builders and ServiceLoader-based module discovery.
Added Jackson 2 compatibility fixtures + a regression spec ensuring Jackson 2-written files still parse under Jackson 3.
Bumped published version and refreshed dependency-report artifacts; removed stale/generated root-level pom.xml.

format/src/main/kotlin/io/spine/format/JacksonSupport.kt:58

In the KDoc instructions, [Format] is linked twice in a row (“extends [Format], nesting it under the [Format] class”). This is a minor readability issue and one of the links can be replaced with plain code formatting to avoid repetition.

Replace the second `[Format]` link with plain prose (flagged by both the `review-docs` gate and the Copilot review), and de-duplicate the "other ... other" phrasing in the `mapperBuilder` documentation — the last two cosmetic items disclosed in the pull request description.
