Errors trying to build, run Java runtime tests on fresh M1 mac with java 16

See original GitHub issue

I get with this error via command line:

$ mvn -DskipTests clean install

Adding a series of these to maven-compiler-plugin from this doc doesn’t help:

Ok, I will try to just build within intellij for now. It looks like it might be a problem to merge the PR because java 8 does not like those parameters or something as it’s not compiling.

Also, it seems like Java 7 does not support compilerArgs in pom. I think it’s the right time to update it, see https://github.com/antlr/antlr4/discussions/3369
