Summary

Upgrades dotCMS to run on Java 25 runtime and compiler, with comprehensive dependency updates and compatibility fixes. This is a spike to test Java 25 compatibility and document any breaking changes.

Closes #33865

Changes

Java Runtime & Compiler

  • Java version: 21.0.8-ms → 25.0.1-ms
  • Compiler release level: 11 → 25
  • Docker base image: Updated to Java 25
  • SDKMAN config: Updated to Java 25

Dependency Updates (Java 25 Compatibility)

  • ByteBuddy: 1.14.15 → 1.18.1 (Java 25 bytecode support)
  • Mockito: 5.12.0 → 5.20.0 (Java 25 compatibility)
  • Jersey: 2.28 → 2.47 (JAX-RS implementation)
  • GraalVM: 22.3.3 → 25.0.1 (migrated to new polyglot API)
  • Glowroot: 0.14.2 → 0.14.0-beta.3 (Java 25 profiler support)

JVM Configuration

  • Added module system opens for Java 25:
    • --add-opens java.base/jdk.internal.loader=ALL-UNNAMED
    • --add-opens java.base/jdk.internal.misc=ALL-UNNAMED
    • --add-opens java.base/jdk.internal.module=ALL-UNNAMED
  • Added ByteBuddy experimental flag: -Dnet.bytebuddy.experimental=true

GraalVM JavaScript Engine

  • Migrated from legacy org.graalvm.sdk:graal-sdk to org.graalvm.polyglot:polyglot
  • Simplified JsEngine.java for new polyglot API
  • Removed deprecated JsDynamicObjectUtils.java
  • Added agent warning suppression on startup

Build & Testing

  • Updated immutables generation to run before integration tests
  • Added generated sources to build lifecycle
  • Disabled fail-fast in CI test matrix for complete reporting
  • Skipped flaky E2E tests unrelated to Java 25
  • Tika plugins kept on Java 11 for compatibility

CI/CD

  • Updated GitHub Actions test phase configuration
  • Added Tomcat environment variable configuration for module opens

Test Plan

  • Build dotCMS container with Java 25
  • Run full integration test suite
  • Run Postman API tests
  • Verify E2E tests (non-flaky)
  • Test JavaScript engine functionality
  • Verify reindexing operations
  • Check Glowroot profiler functionality

Breaking Changes

  • Minimum Java version: Now requires Java 25 runtime
  • GraalVM API: Applications using custom JavaScript engine integration may need updates
  • Tika: Maintained on Java 11 (isolated plugin)

Migration Notes

For developers upgrading local environments:

# Update SDKMAN Java version
sdk install java 25.0.1-ms
sdk use java 25.0.1-ms

# Rebuild with new compiler
./mvnw clean install -DskipTests

Skip two E2E tests that are failing due to known flaky test issues
tracked in #33211, not related to Java 25 runtime changes:

- breadcrumb.spec.ts: "should display correctly on the Content Types page"
  (login button remains disabled)
- portletIntegrity.spec.ts: "Validate the API link in search query modal"
  (popup event timeout)

These tests will be re-enabled once #33227 is merged.

Changed fail-fast from true to false in the test matrix strategy
to allow all test suites to complete even if one fails, providing
a complete test report.
