This change made in Quarkus 3.23.x broke native compilation for apps that use quarkus-groovy. It's used by camel-quarkus-groovy, which is a supported extension in RHBOAC. So it's a potential problem for the upcoming 3.27 LTS.

I currently have a workaround in place that automatically adds --report-unsupported-elements-at-runtime. But as per this comment from sgehwolf@redhat.com, perhaps the original Add-Opens change could be reverted from Quarkus in the 3.x stream?
