June 2025: Cross-repo build stability and Java compatibility improvements across six Google Cloud Java libraries. Key features delivered include (1) centralized GraalVM configuration for google-storage-nio to streamline native-image builds, (2) Arrow dependency compiler flags added for JDK 9+ compatibility in google-bigquery, (3) GraalVM 24 object-instantiation workaround implemented in google-http-java-client to restore expected behavior, (4) hermetic build action versioning stability strengthened in google-storage, and (5) migration to Maven metadata-based latest-version inference for gapic-generator-java. Major fixes addressing newer-JDK environments include temporary disabling of ErrorProne checks for JDK 24+ in java-pubsublite and java-datastore builds to maintain uninterrupted CI. Overall impact includes reduced build failures on newer Java versions, smoother upgrade paths, and more reliable CI pipelines. Technologies/skills demonstrated include GraalVM/native-image tuning, JDK compatibility strategies, build tooling adjustments (ErrorProne flags, compiler flags), Maven metadata-driven versioning, and CI hermetic-build practices.
