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.
With kind regards,
Egon
