## Summary Java 17 support has been dropped in Camel core. This repository already builds on Java 21 (`javaVersion` in the root `pom.xml`, the CI workflows, `AGENTS.md`), so this PR only removes the leftover Java 17 references. JIRA: https://issues.apache.org/jira/browse/CAMEL-22996 ## Changes One commit per change: 1. **Use Java 21 base image for JKube builds** The root `pom.xml` set `jkube.generator.from` to `registry.access.redhat.com/ubi9/openjdk-17:latest`. It now uses `ubi9/openjdk-21:latest`, so container images built by the examples no longer run on a JDK older than the baseline. No module overrides this property. 2. **Remove hardcoded Java 17 release from loggingtracer** `observation/loggingtracer` was the only module that set `maven.compiler.release` to 17. The property is removed. 3. **Update README prerequisites to Java 21** `salesforce`, `genai-observability` and `aot-basic` (GraalVM download instructions) now say Java 21 instead of Java 17. ## Notes for reviewers - `observation/loggingtracer` has no `<parent>`, so it does not inherit `javaVersion` (21). Without the property, the compiler level falls back to the `maven-compiler-plugin` default. The module still compiles, but the classes are now Java 8 bytecode (class file major version 52). If you prefer Java 21 bytecode there, the module can either get the `examples` parent or set the release explicitly. I can add that if you want it in this PR. - I left `azure/pom.xml` unchanged. It sets `maven.compiler.source/target` to 8, which is not a Java 17 reference, and the build passes. - A repo-wide search for Java 17 / JDK 17 / `openjdk-17` finds no remaining references. ## Testing On JDK 21.0.9 (Temurin): - `./mvnw -V --no-transfer-progress clean install -DskipTests`: BUILD SUCCESS, all 102 modules, including `loggingtracer`. - `./mvnw -V --no-transfer-progress test`: BUILD SUCCESS, no test failures. I did not build or run any container image with the new `openjdk-21` base image. I only confirmed that the image exists in the Red Hat catalog. --- _Claude Code on behalf of Aurélien Pupier_ -- This is an automated message from the Apache Git Service.
