  • https://github.com/docker-library/openjdk/issues/505

  • https://github.com/docker-library/docs/pull/2162

  Switching Docker base image to eclipse-temurin AdoptOpenJDK java built on top of debian:bullseye-slim.

• Change base image to eclipse temurin JRE not JDK. The JDK is overkill and could introduce unnecessary security issues.
