Nonetheless, I still consider it superior to having these warnings emitted, and it fairly cleanly just turns off logging of these messages. The main downside is it turns them off globally so non-groovy related warnings and maybe other messages of interest from the same logger would also not be emitted. Cheers, Simon
Can we get rid of illegal reflective access operation warnings?
Hi, It's long overdue, but the status quo is not really nice. Running Groovy on Java 9+ gives warnings like this: WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by org.codehaus.groovy.vmplugin.v7.Java7$1 (file:/tmp/groovy-2.5.3/target/groovy-2.5.3/lib/groovy-2.5.3.jar) to constructor java.lang.invoke.MethodHandles$Lookup(java.lang.Class,int) WARNING: Please consider reporting this to the maintainers of org.codehaus.groovy.vmplugin.v7.Java7$1 Or WARNING: Illegal reflective access by org.codehaus.groovy.reflection.CachedClass (file:/home/tcagent1/agent/work/668602365d1521fc/subprojects/ivy/build/integ%20test/lib/groovy-all-2.4.12.jar) to method java.lang.Object.finalize() WARNING: Please consider reporting this to the maintainers of org.codehaus.groovy.reflection.CachedClass 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 I know it's hard to get rid of those, but we have to do something. Unfortunately I don't have the expertise here...
