------------------------------------------
Aha, so this is expected in Groovy 5. Thank you!
The Groovy Plugin in Intellij IDEA needs to be updated to reflect this changed

> Key: GROOVY-11794
> URL: https://issues.apache.org/jira/browse/GROOVY-11794

> Environment: Linux, Java 17
> Reporter: Mattias Reichel
> Priority: Major
>
> This code fails to compile statically with Groovy 5 but does so successfully
> with Groovy 4.
