Recommended way to install older version of Java (Java 8) in Ubuntu 18.04 (with flexibility to upgrade 18.04)

I am aware of how to install Java 8 in Ubuntu 18.04. The issue is that, now I want to upgrade to say Ubuntu 19.04, but Ubuntu is not letting me do it unless I update openjdk as well.

$ sudo apt list --upgradable

What is the recommended way to install Java 8 in Ubuntu that doesn't interfere with Ubuntu upgrade. For example I would like to use software development tools in my latest Ubuntu. But could I keep a separate docker or VM that has Java 8. I am hoping to have less performance penalty while having the benefit that I could use all other tools and data (not present in that docker image or VM).
