The information in the table in the Versions section of https://libgdx.com/wiki/articles/java-development-kit-selection seems accurate to my knowledge (after it was updated in #198), except that by versions it is referring to the JDK version when I think language level is more appropriate (although maybe not for stuff about DCEVM and the notes about oracle licensing and which JDKs are LTS)
- According to the readme from gdx-liftoff, all stable JDK releases from 8 to 22 work (I'd keep the part about LTS releases being recommended though), but JDK 17 or higher is recommended because the newer android tools versions used require a JDK of 17 or higher.
