Package: groovy Version: 2.4.16-2 Severity: normal Dear Maintainer,
with OpenJDK 11 (which seems to be the default in Buster) Groovy gives a warning at start up time, for any Groovy script. $ groovy -e "foo = \"Foo\"" WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by org.codehaus.groovy.reflection.CachedClass (file:/usr/share/groovy/lib/groovy-2.4.16.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 This is not the case with Java8 and may have to do with classes removed in Java11? Setting JAVA_HOME to have it use Java8 removes the warning. The scripts do seem to run fine otherwise.
