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! -- This message was sent by Atlassian Jira (v8.20.10#820010)
