How will this feature request benefit CircleCI jobs using this image? Will allow Java 21 builds without the overhead of manually installing Java

Describe the solution you would like to see A convenience image for OpenJDK 21

Describe alternatives you have considered Manual installation in each job.

There is no stable java 21 version from Temurin but there are some nightly beta versions. Based on the latest nightly version and already existing java 20 Dockerfiles I have created a fork with implementation for java 21.

Fork: https://github.com/CircleCI-Public/cimg-openjdk/compare/main...bc-tayvs:cimg-openjdk:jdk21

Terium binaries: https://github.com/adoptium/temurin21-binaries/releases

Oh I see. "GA" really is depending on which distribution you're looking at. I'll wait patiently until temurin gets a release out.

In the meantime, we are able to make use of this orb to install the 21-open version in our jobs.
