When an application tells you that you need Java 12, but your repository only has Java 8, it's fine to install whatever implementation of Java 12 you can find from a reliable source. If you feel overwhelmed by the choices, then the easy answer of which Java implementation you should install is whichever is easiest for you to install.
The IcedTea project is essentially OpenJDK, but its goal is to make it easier for users to build and deploy OpenJDK when using fully free and open source tools.

The good news is that you have many options, and this article covers them all. Because Java is such a popular backend for so many applications, it's good to understand the different ways you can install it.
