Description

Brings the Java server onto a coherent 1.0 stabilization baseline centered on Spring Boot 4.1.1 and Spring Modulith 2.1.1. This is a coordinated runtime, framework, integration, test, and build-tool upgrade rather than a collection of isolated version bumps: dependency mediation, database tooling, generated contracts, authentication nullness, and graceful-shutdown ordering were reviewed together.

No compatibility shim, warning suppression, or permanent PostgreSQL override is introduced. The operator-facing behavior and deployment contract are unchanged.

Fixes #1581

Version inventory

“Latest stable” was checked against Maven Central metadata on 2026-08-29. Milestones, release candidates, snapshots, and excluded major migrations are not treated as stable upgrade targets.

Framework and runtime

Dependency Before This PR Latest stable Status / ownership
Spring Boot 4.0.7 4.1.1 4.1.1 Current stable; parent/BOM remains authoritative
Spring Modulith 2.0.0 2.1.1 2.1.1 Current stable; explicitly aligned with Boot 4.1.1
Spring Framework Boot-managed 7.0.9 Boot-managed One resolved Spring generation; no local override
PostgreSQL JDBC 42.7.12, locally overridden 42.7.13 42.7.13 Current stable; redundant local override removed in favor of the Boot BOM
Liquibase core 5.0.3 5.0.4 5.0.4 Aligned with the Hibernate integration and Maven plugin
Liquibase Hibernate 7 5.0.3 5.0.4 5.0.4 Current stable; matches Liquibase core 5.0.4
ShedLock 5.16.0 7.9.0 7.9.0 Major included after a mechanical compatibility review and complete test pass

Integrations and observability

Dependency Before This PR Latest stable Status / gap
Auth0 Java JWT 4.5.2 4.6.0 4.6.0 Current stable
JGit 7.6.0.202603022253-r 7.7.1.202607240634-r 7.7.1.202607240634-r Current stable; also the version selected by Modulith 2.1.1
NATS Java client 2.25.2 2.26.2 2.26.2 Current stable
Slack Bolt 1.48.1 1.50.0 1.51.0 One minor behind: 1.51.0 was published after this branch’s tested dependency snapshot
Sentry Spring Boot 4 starter 8.41.0 8.53.0 8.54.0 One patch behind: 8.54.0 was published after this branch’s tested dependency snapshot
springdoc OpenAPI 3.0.3 3.1.0 3.1.0 Current stable; known upstream warning documented below
OkHttp BOM 5.3.2 5.5.0 5.5.0 Current stable

Test and build tooling

Dependency Before This PR Latest stable Status / ownership
ArchUnit 1.4.2 1.5.0 1.5.0 Current stable; version managed without downgrading Modulith’s runtime scope
JaCoCo 0.8.14 0.8.15 0.8.15 Current stable
OpenAPI Generator Maven plugin 7.19.0 7.25.0 7.25.0 Current stable; generated output reviewed
Maven distribution 3.9.12 3.9.16 3.9.16 Current stable 3.x; Maven 4 remains pre-release
Maven Wrapper implementation Takari 0.5.6 Takari 0.5.6 Wrapper 3.x exists Deliberately unchanged because Maven Wrapper 3 is excluded by #1581

Honest recency gaps

The branch is complete against the dependency snapshot it was built and fully tested with, but Maven Central has since published two newer releases:

Gap Assessment
Slack Bolt 1.50.0 → 1.51.0 No compatibility blocker is recorded; this is new dashboard work rather than a hidden claim that 1.50.0 is still latest
Sentry 8.53.0 → 8.54.0 No compatibility blocker is recorded; this is a newly available patch after the tested snapshot

This table is intentionally explicit: the PR does not claim that every selected version remains the newest artifact indefinitely. Reviewers can choose to absorb these two late releases here, at the cost of invalidating the current tested snapshot, or let Renovate handle them as fresh follow-up updates.

Compatibility review

Area What changed Evidence and result
Spring generation Boot 4.0.7 → 4.1.1; Modulith 2.0.0 → 2.1.1 Modulith 2.1.1 explicitly upgrades to Boot 4.1.1, Framework 7.0.9, and JGit 7.7.1. The resolved tree contains one Spring generation. The attention-required Gradle protobuf/gRPC item in Boot 4.1.1 does not apply to this Maven build.
ArchUnit mediation Core upgraded to 1.5.0 Managed in dependencyManagement, preserving the runtime scope Spring Modulith deliberately supplies; avoids a test-only production classpath regression described by Spring Modulith #1329.
PostgreSQL and Liquibase JDBC 42.7.13; Liquibase stack 5.0.4 Boot owns the driver version. Liquibase core, plugin, and Hibernate integration are aligned. PostgreSQL-backed migration and integration tests pass.
ShedLock 7 5.16.0 → 7.9.0 The code does not use the moved DatabaseProduct or deprecated timezone API, continues to use database time, and matches the upstream compatibility matrix for Java 21 / Spring 7 / Boot 4. No deferral is needed.
Graceful shutdown Boot lifecycle constant changed Migrated to WebServerApplicationContext.GRACEFUL_SHUTDOWN_PHASE; regression tests assert relative ordering for workers, WebSockets, and webhook publishing rather than copying a numeric phase.
Authentication nullness Spring APIs expose nullable results more precisely Resolver return nullness is declared, and required OAuth registration values are checked at their request-processing boundary. No compatibility layer or warning suppression was added.
Hibernate test profile Explicit H2 dialect removed Hibernate infers the dialect from JDBC metadata; obsolete configuration was deleted rather than retained as a shim.

Generated-contract review

Artifact Result
server/openapi.yaml Regenerated from the upgraded application; validation-only changes: slug bounds plus positive model token bounds aligned with the agent runtime
webapp/src/api/** Regenerated with OpenAPI Generator 7.25.0; no tracked client diff
Unrelated generated churn None accepted
Idempotence Re-running specification and client generation leaves the reviewed tree unchanged

Known springdoc warning

springdoc 3.1.0 repeatedly logs Json Processing Exception warnings while cloning OpenAPI 3.1 schemas, including failures to deserialize scalar type values into the swagger-models 2.2.41 Set<String> representation. This is tracked upstream in springdoc-openapi #3314. The warnings are noisy but non-fatal: generation completes, the reviewed specification contains the expected constraints, a second generation is idempotent, and the generated client has no tracked diff. This PR deliberately does not hide the condition with log suppression, downgrade springdoc, or introduce a local compatibility shim; the upstream issue remains the owner.

Deliberate exclusions

Excluded work Why it is not in this PR
PostgreSQL server 18 Explicitly excluded by #1581; this PR validates the JDBC/Liquibase stack against the repository’s supported PostgreSQL test container
Maven Wrapper 3 Explicitly excluded by #1581; Takari Wrapper 0.5.6 cannot enforce the modern wrapper/distribution checksum properties, and adding ignored properties would be security theatre
Docker base images Explicitly excluded by #1581
Frontend dependencies Explicitly excluded by #1581; the webapp client was regenerated only to detect contract churn

Verification

Local evidence

Gate Result
bun run format Pass
bun run check Pass
bun run verify Pass: checks, server verification, 992 webapp tests, 1,625 Storybook tests, production builds, and docs build
./mvnw test -Parchitecture-tests -DskipCoverage=true Pass: architecture and Modulith verification
MANAGEMENT_PORT=0 SERVER_PORT=0 ./mvnw verify -DskipCoverage=true Pass: full unit and integration lifecycle, including PostgreSQL and Liquibase

./mvnw dependency:tree review No unintended Spring, Liquibase, PostgreSQL, or ArchUnit conflict
Model token-bound contract test Pass: all four create/update request DTOs reject 0 and accept 1
OpenAPI and webapp client regeneration Pass: all eight token-bound fields emit minimum: 1; no unrelated client churn

GitHub evidence

Gate family Result
Quality and generated-artifact checks Pass
Unit, architecture, integration, E2E, and Storybook tests Pass
Dependency, secret, policy, CodeQL, and mutation-security checks Pass
Application and webapp container builds Pass
Compose, changeset, title, and repository-policy checks Pass

Checklist

  • The empty changeset explains why no operator- or user-facing release note is needed.
  • No operator action, new required environment variable, manual migration, compatibility shim, warning suppression, or permanent PostgreSQL override is introduced.
  • The branch is rebased onto main, has no merge conflicts, and all required automated checks pass.

Summary by CodeRabbit

  • New Features

    • Added stricter validation for group and practice slugs, requiring lowercase hyphenated values between 3 and 64 characters.
    • Added validation requiring LLM context windows and maximum output tokens to be at least 1.
    • Added non-negative validation for display order, review artifact IDs, and achievement progress values.
  • Bug Fixes

    • Improved handling of missing OAuth configuration with clearer validation errors.
    • Improved graceful shutdown ordering for workers and webhooks.
