Would it be possible to create a version for JDK17?

I thought I'd got my build working with JDK17 following your example (using Zulu on Windows), but when I run in GitHub Actions (Zulu on Ubuntu) Surefire bombs out with the message: Cannot use JVMCI compiler: No JVMCI compiler found.
It is unclear what the implications of removing JVMCI are for polyglot programming on OpenJDK.

Oh, actually I think I might have just resolved my issue.
In the pom you have:
--upgrade-module-path=${compiler.dir}/compiler.jar:${compiler.dir}/compiler-management.jar
To work on Windows that needs a semicolon:
--upgrade-module-path=${compiler.dir}/compiler.jar;${compiler.dir}/compiler-management.jar

The docs (https://docs.oracle.com/en/java/javase/17/docs/specs/man/java.html) are quite specific that is should be a semicolon, but that definitely doesn't work on Linux.
Fortunately the docs also state that it's a list of directories, so this seems to work:
--upgrade-module-path=${compiler.dir}

I guess this has been adjusted in b690c6c, now.
