---------------------------------------
Summary: 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
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!
