Summary

Cuts services/report-service over from Java 8 / Spring Boot 2.5.15 to Java 17 / Spring Boot 3.2.12 (TTRWRKS-17). The bulk is OpenRewrite's UpgradeSpringBoot_3_2 recipe (javax.*jakarta.*, JUnit 4 → 5, SpringFox → springdoc, HttpClient 4 → 5, Security 5 → 6 lambda DSL); the rest is the hand-fixing the recipe can't do:

  • Security 6 headers DSLXXssConfig.block(boolean) no longer exists, and the recipe also nested contentTypeOptions() inside the frameOptions lambda:
    .headers(h -> h
        .frameOptions(f -> f.deny())
        .contentTypeOptions(c -> {})
        .xssProtection(x -> x.headerValue(HeaderValue.ENABLED_MODE_BLOCK)))
    Swagger matchers moved with it: /swagger-resources/**, /v2/api-docs/**/swagger-ui.html, /v3/api-docs/**.
  • HttpClient 5 timeoutsHttpComponentsClientHttpRequestFactory.setReadTimeout(int) is gone in Spring 6; the socket timeout now lives on the pool via ConnectionConfig, and the connect timeout takes a Duration.
  • springdoc bean — the recipe deleted the SpringFox Docket but left apiInfo() orphaned and private; re-exposed as @Bean OpenAPI.
  • Dead config — dropped the SpringFox spring.mvc.pathmatch.matching-strategy=ant-path-matcher workaround and the explicit hibernate.dialect (Hibernate 6 auto-detects), and unquoted springdoc.packages-to-scan, which the recipe emitted with literal quotes.
  • Build hygiene — removed the recipe's redundant httpclient5.version / surefire pins now managed by the Boot parent.

CI: the report-service job in ci.yml moves from Temurin 8 (mvn compile/test/package) to Temurin 17 with maven caching and a single mvn -B verify; the report-service-tests gate in docker-build.yml moves to 17 as well. Dockerfile builder/runtime are maven:3.9-eclipse-temurin-17 / eclipse-temurin:17-jre.

Docs/comments that asserted "Java 8 / Spring Boot 2.5" (README service table, docs/CI_STRATEGY.md, docs/SDLC-COVERAGE.md, Helm chart description, .trivyignore, per-class "LEGACY PATTERNS" headers) are updated to the new baseline; remaining tech debt (iText 5, POI 4.x, Guava 28, Commons IO 2.6, java.util.Date) is left in place and noted as follow-up.

No modernization sweeps: no records/var, no JPMS, no --add-opens needed. Local mvn verify on JDK 17: 50 tests, 0 failures, 1 skipped.

🟡 Report metrics remain uncollectable

requestMatchers permits /metrics, while Spring exposes metrics at /actuator/prometheus. The ServiceMonitor requests /metrics, so every Prometheus scrape receives 403.

Checked this — it's pre-existing, not something this migration changed, so I've left it alone.

origin/main already had .antMatchers("/health", "/metrics", "/actuator/**").permitAll() and already exposed health,info,prometheus; this PR only renames antMatchersrequestMatchers. The monitoring.path: /metrics in the Helm values is also unchanged here, and every other service chart in the repo (file-service, document-service, …) uses the same /metrics path. Note also that /metrics is permitted, not blocked — an unmapped permitted path returns 404, not 403, and /actuator/prometheus is reachable via the /actuator/** matcher.

So the ServiceMonitor path is a repo-wide charting question rather than a regression introduced by the Java 17 cutover; changing it here would be an out-of-scope behavioral change to Helm values that ship from upstream. Flagging as a follow-up instead.

📝 Info: Timeout migration preserves both bounds

ConnectionConfig applies the 30-second socket timeout across pooled routes. The request factory retains the five-second connection timeout.

📝 Info: Converted tests still execute

Surefire selects JUnit Platform and runs all seven classes. The suite completes 50 tests, with only the opt-in transcript test skipped.

📝 Info: Unmatched requests remain denied

Omitting anyRequest preserves the restrictive fallback. Unmatched paths return 403, while every declared public route remains reachable.

…lusion

The module no longer builds on JDK 11, and without Nashorn the script-lookup case errors instead of evaluating; baseline re-recorded for that case only.
