Me stubborn and tired! Groovys complaint is valid!

>             Project: Groovy
>          Issue Type: Bug
>         Environment: Mac OS X Version 17.5 (19618.2.12.11.6)
>            Reporter: Tommy Svensson
>            Priority: Critical

> Now I have debugged over and over and over to finally find this:
>                Map<String, Object> map = [:]
> 		...
>                 LinkedHashMap<String, Object> resMap = new LinkedHashMap()
>                 resMap.putAll( map ) <=== This is the one producing:
> WARNING: An illegal reflective access operation has occurred
> WARNING: Illegal reflective access by org.codehaus.groovy.vmplugin.v9.Java9 (file:/Users/tommy/.m2/repository/org/apache/groovy/groovy/4.0.21/groovy-4.0.21.jar) to field java.lang.reflect.Proxy.h
> WARNING: Please consider reporting this to the maintainers of org.codehaus.groovy.vmplugin.v9.Java9
> WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
> WARNING: All illegal access operations will be denied in a future release
> This seems like very legal code to me! 
> I can also add that when single-stepping through the code in debugger (IDEA) the above does not occur! No warning displayed!
> This makes me believe that the problem occur if run to fast! Since there is a Groovy specific plugin involved here I'd say this is a Groovy problem!
> I can also add that I'm working on an Apple M1 Pro (I think Apple call it). 64 GB memory and 10 core processor. It is really fast! I believe that this is relevant due to working fine when run slower in debug mode.
> I do consider this a Groovy issue!
