Month: 2025-05 — concise monthly summary focusing on business value and technical achievements across the quarkusio/quarkus and hibernate/hibernate-orm repositories. Key outcomes include delivering ORM 7.0 readiness and cleanup, enhancing runtime checks and test hygiene, tightening configuration safety, and aligning dependencies with the latest Hibernate ecosystem. This period also modernized the build/toolchain, improved release automation, and clarified release processes for faster, safer deployments. Highlights by repository: - quarkusio/quarkus: • Hibernate ORM 7.0 readiness and cleanup: API cleanup (CDI metamodel exposure removal), internal dead-code removal in Panache, and upgrade to CR2 dependencies. (Commit messages include: Do not expose Hibernate-specific metamodels through CDI; Upgrade to Hibernate ORM 7.0.0.CR2 / Hibernate Reactive 3.0.0.CR2; Remove some dead code in Panache using Hibernate ORM internals.) • Hibernate Reactive runtime: database version checks and test cleanup: Adds runtime DB version checks (default enabled), refactors dialect resolution, and test cleanup. (Commits include: Support DB version checks (enabled by default) with Hibernate Reactive; Remove nonsensical text from application.properties in Hibernate Reactive integration tests.) • Quarkus integration: unsupported properties override warnings: Introduce warnings when unsupported properties override Quarkus configuration in Hibernate ORM and Reactive extensions. (Commit: Allow "unsupported properties" set in the Hibernate ORM/Reactive extension to override Quarkus' own values.) • Hibernate Search 8 upgrade compatibility: Upgrade Hibernate Search dependencies to 8.0.x and align Elasticsearch-related code with new API signatures. (Commit: Upgrade to Hibernate ORM 7.0.0.Final / Hibernate Reactive 3.0.0.Final / Hibernate Search 8.0.0.CR1.) - hibernate/hibernate-orm: • Build system and JDK toolchain upgrades and standardization: Consolidates and upgrades JDK tooling, builds configuration, and logging; updates to JDK max versions, ensures toolchain consistency; includes test-mode bytecode adjustments and verbose JDK logging. (Commits include: Clarify toolchain support; Require JDK 21 for building (but keep the Java 17 baseline); Don't ignore 'orm.jdk.max' from gradle.properties; Actually produce Java 24 bytecode in tests when testing against JDK 24; Log JDK version information at the start of every build; Remove redundant version requirements in hibernate-jfr.) • Automated release workflow enhancements: Adds CI/CD automation for Jira-based releases and improves release gating to skip automatic releases when no releasable commits exist. (Commits: Use a script to release on Jira; Avoid auto-release when there are no "releasable" commits.) • Documentation and release process consolidation: Centralizes release instructions and improves CI/CD readability by updating docs and refactoring Jenkins pipeline stage names. (Commits: Centralize release instructions in MAINTAINERS.md; Clearer stage names in release process.) Overall impact: - Increased stability and forward compatibility with the Hibernate suite (ORM 7 / Reactive 3 / Search 8) and the Quarkus integration, reducing risk and maintaining alignment with upstream changes. - Improved runtime resilience via database version checks and clearer configuration behavior; enhanced test hygiene to prevent flaky tests. - Clearer release processes and automation that reduce noise in releases and enable Jira-driven workflows. - Modernized toolchains and CI/CD practices, enabling building with newer JDKs and producing consistent bytecode across environments. Technologies/skills demonstrated: - Java toolchains and Gradle-based builds with JDK 21+ and Java 24 bytecode testing - Hibernate ORM 7.x, Hibernate Reactive 3.x, and Hibernate Search 8.x integration - Quarkus integration patterns and configuration safety (unsupported properties overrides) - CI/CD automation and Jira-based release workflows - Elasticsearch API adaptation and upstream API alignment
