Summary

Upstream check against Azul's Zulu metadata API found a newer GA build for the Java 21 line.

Before After
Zulu build zulu21.54.107-ca-jdk21.0.13 zulu21.54.109-ca-jdk21.0.13.0.3
OpenJDK version 21.0.13 21.0.13.0.3

Also checked and confirmed already up to date (no changes needed):

  • Java 11: zulu11.92.109-ca-jdk11.0.33 matches Azul's current latest release.
  • base.image (gcr.io/distroless/cc-debian13:debug) digest matches current upstream digest for both java-11 and java-21.

Changes

  • java-21/java.version: bumped to zulu21.54.109-ca-jdk21.0.13.0.3.
  • java-21/Dockerfile: updated ZULU_SHA256_AMD64 / ZULU_SHA256_ARM64 pins to match the new build (sha256 values sourced from Azul's metadata API sha256_hash field), updated comment example.

Verification

  • Confirmed SHA256 values against Azul metadata API (api.azul.com/metadata/v1/zulu/packages/{uuid}).
  • Built java-21 image locally (docker buildx build --platform linux/arm64) with the updated build args — build succeeds, blocked.certs fingerprint check passes.
  • Ran java -version in the built image: outputs openjdk version "21.0.13.0.3".

Remove dead top-level ARG JAVA_VERSION
b4390ac 
Left over from 3f62f1d which replaced 'FROM azul/zulu-openjdk-debian:${JAVA_VERSION}'
with 'FROM debian:trixie-slim' + a stage-scoped ARG JAVA_VERSION redeclaration for use
in RUN. No FROM instruction consumes the top-level declaration anymore; verified builds
emit no missing-build-arg warning for JAVA_VERSION after removal.

Added a follow-up commit removing dead code found by auditing the last 10 commits:

  • Dead top-level `ARG JAVA_VERSION` in both `java-11/Dockerfile` and `java-21/Dockerfile`. Traced to commit 3f62f1d (eMudhra blocklist fix), which replaced `FROM azul/zulu-openjdk-debian:${JAVA_VERSION}` with `FROM debian:trixie-slim` + a stage-scoped `ARG JAVA_VERSION` redeclaration for use in `RUN`. The original top-level declaration (only needed for substitution into a `FROM` line) was left behind and is no longer consumed anywhere.
  • Verified: both images rebuild cleanly with no missing-build-arg warning for `JAVA_VERSION`, and `java -version` still reports the correct versions (21.0.13.0.3 / 11.0.33) after removal.

Left the per-arch `base-amd64`/`base-arm64` stage duplication as-is — that was intentionally added in #28 for multi-arch support, not dead code, just boilerplate that could be unified later if desired.
