We are experiencing in latest wildfly UBI9 images missing NO_PROXY environment variable. Investigating revealed 3 env vars from description were removed. For details check:

• UBI8 proxy API https://github.com/jboss-container-images/openjdk/blob/ubi8/modules/proxy/api/module.yaml
• UBI9 proxy API https://github.com/jboss-container-images/openjdk/blob/ubi9/modules/proxy/module.yaml

As far as I can tell environment variables are upper cased. So removal upper cased variant in favour of lower case is at least inconsistent. Change was introduced here https://github.com/jboss-container-images/openjdk/commit/db91e12eab349b07d148a03835b4ce11b68ad9ad.

At least we would need to document in our release notes. Or maybe better. Can we reference some JDK image release notes describing those changes?
