Additional context
The packages java-17-openjdk-devel java-17-openjdk-jmods are no more available for centos 7, not even in the centos archive.
We see two solutions:
1- Revert to openjdk 11
2- Upgrade to centos 8 (but we need to evaluate if openshift 3.11 will work as expected in centos 8, because upgrading the underlying os of the host to centos 8 would be mandatory).

We’ve found a solution to our problem.

AdoptOpenJDK moved to the eclipse foundation and its name is now Eclipse Temurin, by Adoptium.

https://adoptopenjdk.net/installation.html

There is a guide to install the new packages in a CentOS/RHEL/Fedora distro:

https://adoptium.net/es/installation/linux/

And the packages repository contains packages for centos 7:

https://packages.adoptium.net/ui/native/rpm/centos/7/x86_64/Packages/

So, we could install it more or less easily in our centos 7 and ubi 8 images.

We are still evaluating solutions, but I wanted to write it here so all of us know about this one.
