Run CI on more recent Java versions and different runtimes

[jord1e]

There should probably be tests for on more recent builds of OpenJDK v8, LTS 11, and LTS 17. Potentially even on JDK (pre-release) 18
and the OpenJ9 (and GraalVM runtimes).

If there is support, I have time at the end of next week to contribute this. Let me know 😃 .

By all means if your willing to make a PR to get this running that would be great.

The JVM platform has proven remarkably stable for us. We started on JDK 6 and then 8 and have not had ANY reports of compatibility problems or runtime issues that I can recall.

Five MultiSourceReader tests are actually failing when running on JDK 16+, even when compiling with JDK 8. You could say that the effort is paying off 🥲

I think it is coming from https://bugs.openjdk.java.net/browse/JDK-8241020 but I am not sure. This will probably require a good amount of time for me.
