I frogot that the tests are failing because github actions doesn't have the exploded classes. Should we extract the lib/modules of the system jdk before running them? On my laptop it takes exactly 1 second to do so.

-- Found Java: /usr/lib/jvm/adoptopenjdk-11-hotspot-amd64/bin/java (found suitable version "11.0.11", minimum required is "1.8")

CMake detects Java 16 on my machine, does that work as well?

If not: java_home -V lists version 8, 11 and 16. Is there an easy way to choose the right one even if it's not the system default?

Cmake detects Java 16 for me, does that work as well?

And I have java 15... We just have to pick one version.

8: no modules
11: lts: many functions removed but modules added
16: jvm.h was split up and some functions were added

Another problem is that we can't modify the system jdk so it will be difficult to use our custom libjvm.so. But I'm sure we can solve that if we ever get there.

find_package(Java 11.0.11 EXACT REQUIRED)

For some reason this fails if 11 is installed but not the system default.

Could we do something like JAVA_HOME = $(/usr/libexec/java_home -v 11) to override the system default? Does that work on your machine?

I think find java already looks at java home so you could set that before calling cmake. I don't have java_home.

I think we also need JAVA_HOME to get the location of lib/modules.
