Eric Milles updated GROOVY-11428:
---------------------------------
Language: groovy
> WARNING: An illegal reflective access operation has occurred
> ------------------------------------------------------------
>
> Key: GROOVY-11428
> URL: https://issues.apache.org/jira/browse/GROOVY-11428
> 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!
