The Java support needed for one of the linting checks is deprecated.

[mmunro-ltrr]

The linting checks in arizona-bootstrap include the Nu Html Checker (vnu-jar), which needs a Java environment to run. To standardize this in a way that works for local development as well as on GitHub actions. The Dockerfile includes this by lifting it from a pre-built standard OpenJDK Docker image, but this is now deprecated
docker-library/openjdk#505

Conditions of satisfaction

Some other mechanism should include an actively maintained Java environment to support the vnu-jar checker.

The recommended replacements are the official images of Eclipse Temurin

@tellison: thanks for the advice — I had looked at those images, but we are currently doing something strange with a

COPY --from=openjdk:11.0.15-jre-slim-bullseye "$JAVA_HOME" "$JAVA_HOME"

in our Dockerfile to lift just part of the old OpenJDK image, relying on both being based on Debian Bullseye. It's probably time to opt for something less fragile instead.
